Thought Experiment: What Would You Do If You Could Relive Your Life With Your Current Memories?

The older I get, the more I wish I could go back in time and tell my younger self that things weren’t as hopeless as they seemed. I would’ve loved to grab my 15-year-old self by the shoulder, looked him right in the eyes, and told him that I had many wonderful experiences ahead of me. I would’ve maybe told him some winning lotto number as well, but that’s beside the point.

Most people who survived adolescents and found ways to thrive in the adult world appreciate the perspective of hindsight. It can be sobering for some, but bittersweet for others. When we’re young, ignorant, and inexperienced, everything just seems more overwhelming. We struggle to make sense of it all. You really can’t hope to understand anything without time, experience, and perspective.

I suspect most people have entertained the idea of sending messages to their younger self at some point in their lives. Even if it’s just to tell them who will win the Super Bowl this year, there’s a lot of wisdom we’d love to impart. Movies like “Groundhog Day” and “Happy Death Day” demonstrate the power of having such hindsight. However, those movies only go so far.

It’s one thing to relive a single day with all your memories intact. An entire lifetime is on a much larger scale with far greater implications. It makes for an interesting thought experiment. Now, after a certain X-Men comic told a remarkable story with this, I’d like to pose it as a formal question.

What would you do if you could live your entire life over again with the same memories, knowledge, and experiences you have now?

It’s a question that is likely to inspire many different answers. Everyone’s life, circumstances, and experiences are different. Some people wouldn’t want to change much. They like how their lives turned out. Others would make significant changes, both for their lives and for others.

Since a scenario like this has so many implications, here are a few specifics to consider before answering this question. I’m going to try and answer it for myself, but I think it’s worth establishing a context, if only to avoid the kind of time travel paradoxes that make the timelines in “Back to the Future” so confusing.

With that in mind, here are the rules for this little experiment:

  1. When you’re reborn, you have all the memories you have up to this point in your life
  2. You’re aware that you were reborn and don’t suffer significant shock from being in a younger body
  3. You keep the fact that you have the knowledge of your future self secret
  4. You assume consciousness in your younger self at around five-years-old, which is when most children start to form lasting memories
  5. You can only be reborn and re-live your life once
  6. Your ability to recall your memories is consistent with your ability to recall general memories at this very moment
  7. You have no hint of knowing how different decisions affect the future course of events for yourself and the world as a whole
  8. The course of events still unfold as you remember them and don’t change unless you directly influence them

With those rules in mind, take a moment to contemplate how you would live your life the second go-around. What would you do initially? How would you change the course of your childhood? How would that change the course of your teenage years? What points in your life would you make radically different decisions?

For me, personally, there are many general aspects of my life that I would change, even from a young age. I would take a very different approach to how I went about everything from school to friends to my little league baseball career. Life experiences has shown me how flawed my mentality was during that time. I focused so much on outcomes over the process that it caused more frustration than growth.

I also developed a very negative outlook for much of my youth and during my teen years. In my defense, I had terrible social skills and some irrational anxieties that only became absurd with the benefit of hindsight. Armed with the experience I have now, I would’ve been a lot more hopeful and optimistic in approaching school, friends, and challenges. I think that would’ve helped me achieve more and learn more.

In terms of specifics, I freely admit that I would use my knowledge of the future for personal gain, albeit to a limited extent. I can’t remember specific lotto numbers for specific dates, but I can remember which teams won the Super Bowl and the World Series. I also remember which companies made the most gains in the stock market. As such, I would invest whatever I could in Apple, Netflix, Amazon, and Google.

That would’ve made paying off my student loan debt a lot easier. It also would’ve spared me some very unpleasant experiences I had when it came to finding decent housing, both in college and after I graduated. Not having to worry about money would definitely have helped with a lot of things. I could use it to take additional classes, invest in my writing career, and avoid some major missteps, of which I’ve made plenty.

I imagine a lot of people would take advantage of that knowledge. Now, there are some arguments that making those kinds of investments and bets often end up changing the outcome, resulting in a time paradox of sorts. That might be the case if you randomly invested a billion dollars in Apple at a time when it was on the brink of bankruptcy, but I imagine it would take a lot to significantly change something like that.

This brings me to the most sensitive aspects of this thought experiment and one I’m sure more than a few people have already imagined. Having the benefits of hindsight means you can fix the mistakes you made in your youth, both in terms of decision and attitudes. What about decisions that might affect the entire course of history?

It’s one thing to profit from a bump in stock prices. It’s quite another to change a key moment in history. It’s the inescapable implications behind the butterfly effect. However, even movies like “Back to the Future” show that you can only affect the course of history to a limited extent. Even in the worst scenario, Marty McFly only messed up Hill Valley in “Back to the Future II.” He didn’t cause a nuclear holocaust.

If you only have your memories of the future and no other abilities beyond that, you’re still going to have trouble changing certain events. A lot of people would probably try to prevent the events of September 11th, 2001, but how would you even go about that? Would calling someone at the FBI or warning the airports be enough? Would going there and trying to stop it directly be effective?

At best, you’ll only delay it. At worst, you might get yourself killed. The same goes for any event. Say you wanted to change the outcome of the 2000 US Presidential Election or, depending on your affiliation, the 2016 Election. These events have many moving parts. There’s only so much you can do to influence them. Even if you shout the warnings from the highest rooftop, you’ll probably won’t be taken seriously.

There’s also the distinct possibility that changing these events will lead to something much worse. That’s what happened in the Stephen King novel, “11.22.63.” In the story, Jake Epping stopped the Kennedy Assassination, but that indirectly led to a nuclear war. There was even an episode of “Family Guy” that explored this concept.

It’s a difficult decision that I’m sure most would wrestle with. Personally, I would make an effort to avert something as terrible as the September 11th, 2001 attacks. I don’t know how I would go about it, but I certainly would try. I would probably do the same for things like the Columbine massacre or other school shootings, if only to save the lives that wouldn’t otherwise be saved.

As for other events, it’s hard to say and even harder to know the implications. If someone has a specific method they would use, please share them in the comments. I think they’re worth discussing.

These are just some of the issues you would face if you had a chance to relive your life all over again. Hindsight offers many benefits and perspectives, but it also comes with risks. You might be able to avoid the mistakes you know about, but you also might end up making others you didn’t anticipation and those could be far worse.

It’s still an interesting though to consider. As we get older, our perspective on the past and present changes considerably. We can never know how we would’ve acted with some added foresight. I like to think that I, along with most people, would’ve used it to become better.

What Will The Currency Of The Future Be?


Most people don’t think about what gives their money value. There’s just a general understanding that it’s vital for basic economic activity. Whether it involves simple bartering or complex cryptocurrencies, the assumptions are the same. Money is a measure of value and exchanging it is how we ascribe value to basic goods and services.

There are all sorts of economic and financial complexities that determine how money works. Rather than bemoan the issue, knowing I am not the least bit qualified to do so, I’d like to focus on the nature of money in the future. Having already given plenty of thought to advanced artificial intelligence, human enhancement, and intimacy, I think it makes sense to contemplate how it all affects our ideas about money.

By that, I’m not referring to current trends in digital currency and older trends within modern banking systems. I’m talking about what money will be in a future where people, resources, and our entire understanding of economics has rendered the existing system obsolete. If you don’t think that’ll ever happen, then I only request that you give some added scrutiny to the concept of money.

I often find myself scrutinizing it whenever I watch a bit too much sci-fi. Some of my favorite sci-fi movies and TV shows of all time don’t give much thought to money. In “Back To The Future II,” a world of flying cars and cheap fusion power still had money. Things were just exceedingly expensive due to inflation. A Pepsi cost around $50.

While inflation is a real force that was certainly present in the non-movie version 2015, it’s somewhat strange that it would get that excessive in a world where fusion power plants could fit into cars made in the mid-1980s. In the real world, advanced technology tends to counter inflation. Logistically, better technology means more efficiency. More efficiency means cheaper goods. Cheaper goods mean lower prices.

We can certainly forgive movies like “Back To The Future II” for failing to understand the economics of money. In addition, the technology of that world wasn’t so advanced that it undercut the foundations of society. However, the money systems in galaxy-spanning space operas can’t make those excuses.

Star Wars” still used some form of currency. It was necessary for Han Solo to pay his debts and for Luke to enlist his services to Alderaan. Other space-faring epics like “Mass Effect” and “Guardians of the Galaxy” have a form of currency that allows characters to be greedy and ruthless. Whether they’re called credits or units, the principles are the same.

There’s this vague concept of money. Everyone agrees that it has value, but there’s little information about why it has value. That’s not entirely flawed. It’s just no different than traditional fiat money, which nearly every modern society utilizes to some extent in the real world. The money isn’t backed by anything. People just collectively agree it’s worth what it says its worth.

Now, I’m not one of those conspiracy theorists who claim this form of money is part of a global conspiracy theory run by lizard people who may or may not have murdered John F. Kennedy. I don’t know enough about economics or finance to make sense of our current monetary system. All I know is that we have a system of money that works within the constraints of our current society.

Whatever you think of that system, there’s still a larger question worth asking. What will money look like in the future when some of those constraints disappear? To some extent, our current system requires that people be frail, products be flawed, and resources be scarce. Through certain advances, some of which may occur in the next 50 years, those limits may disappear.

What happens to money when we perfect advanced energy generation that makes electricity cheap, abundant, and clean?

What happens to money when people begin upgrading their bodies with advanced biotechnology and cybernetic implants?

What happens to money when nanotechnology advances to a point where the production and assembly of every conceivable good is dirt cheap?

What happens to money when advanced artificial intelligence gets to a point where it gets so intelligent that it can solve every conceivable problem and manage every conceivable issue perfectly?

What happens to money when our civilization gets to a point where we can just upload our minds into a perfect simulation where all our wants and needs are met on a whim? Regardless of whether you think we’re already in a simulation, the question surrounding money and what form it takes remains.

While it’s impossible to predict the cumulative impact of technology, especially the kind that subverts modern economic forces, I believe there will be some sort of currency in the future. Even if we perfect nanotechnology, artificial intelligence, and teleportation, I think it’s reasonable to conclude that we’ll need some system for exchanging goods, services, and overall value.

I also don’t think it’s reasonable to assume that our current fiat money would work. Just putting images on paper and using it as a token may not be practical in a society of advanced AI and immortal humans. These days, most of our money exists only as code in a computer and not as piles of paper or gold. I think for any form of money to work in a society of such technology, it needs to be backed by something.

Some sci-fi stories explore that concept. The movie, “In Time,” wasn’t that good, but the idea was intriguing. In that world, everybody is immortal and never ages past 25, but the system is such that the currency is measured in time. In a sense, a dollar is backed by a year of life as a healthy 25-year-old. For most people, that has plenty of value.

The rest of the movie is awful and I don’t recommend it, but it presents a novel, albeit dystopian concept. For that economic system to work, there has to be some sort of tyrannical power structure that has the ability to snuff someone’s life out the second they can’t pay. Even corrupt insurance companies aren’t that bad.

Then, there’s the Netflix series, “Altered Carbon,” which I highly recommend. That world also has a problem with massive wealth disparity, but not in the sense that rich people horde money in giant vaults. In this world, technology has advanced to the point where people can transfer their consciousness to different bodies the same way most people transfer files between computers.

In that world, the most precious assets are the best bodies. Being able to live in the body of Brad Pitt is inherently more valuable than living in the body of Danny DeVito. Much of society, from prisoners to billionaires, is divided by who has access to those bodies. In the story, the super-rich Bancroft family have that access and that’s what makes them so rich.

That kind of wealth may not show up as numbers on a balance sheet, but the value is there. Being able to produce, inhabit, and live within strong, beautiful bodies provides a powerful basis for any currency. Talk to anyone who has dealt with the effects of aging, which is pretty much everyone over the age of 25. Most would gladly pay a premium to live in a stronger, fitter body.

While “Altered Carbon” doesn’t get into the specifics of that system, the principle holds true. In a future where people aren’t bound by the limitations of biology or the human body, the greatest asset they can possess is a medium with which to experience life. A better medium means better experiences. Some companies today are already seeking to provide those experiences. Technology will simply change the methods.

Whether we end up in a simulated utopia or not, the experiences a currency affords us is what will give it value. Even though worlds like that of “Star Trek” present a world where money doesn’t exist, there is still plenty of value ascribed to life experiences. You may not be able to print that on a piece of paper or send that in a wire transfer, but that is still recognized as valuable.

I could still be wrong. Remember, I’m not an expert in money, nor can I predict the trends that future advances in technology will incur. Whatever form it takes, though, I expect that the overall goal will still be the same. We use money to pursue better, more rewarding life experiences. However we go about pursuing is, and always has been to some extent, the only true universal currency.
