If you follow the Tech industry, you know that everyone’s always searching for the Next Big Thing, and if you remember my series on The American Challenge, you might remember that I talked about how that book badly missed on some of its predictions of what The Next Big Thing would actually be. This got me thinking, what do I think the Next Big Thing is? What do I think will be the next trillion-dollar industry, the type of thing countries will want to focus on and people will want to invest in, things like semiconductors and computers in the 80s, mass-built automobiles in the 1910s, or trains in the 1800s. The kind of thing that will change the way we do everything, and if you have a chance to get in at the ground floor you’ll be kicking yourself in 20 years if you don’t take it.

To start with, I’ll talk about others’ predictions.

I’ve heard some people talk about Cloud Computing as the Next Big Thing, but it’s hard to tell if it’s truly Next or if it’s more of a continuation of the Current Big Thing. Like, would it make sense to separate the internet revolution from the computer revolution? Both happened concurrently, the first couldn’t have happened without the second and the second was truly skyrocketted by the first. So how does Cloud Computing fit into all this, it’s already a trillion dollar industry with the largest tech companies in the world all throwing money into it, and even if I can’t explain how it works personally I can definitely see that others are talking about it as a revolution. But again it feels hard to tease it apart from computers and internet as a whole, and it doesn’t seem like we’re on the ground floor anymore. Microsoft, Google, Amazon and Meta have all put so much money into their cloud infrastructure that I don’t see any small fries really taking pieces off of them. I’d say Cloud Computing is the current Big Thing.

But that’s mostly semantics, I’ve also heard people say 3D printing is the Next Big Thing. The University of Nottingham for instance has a department that wants to be able to 3D print a smartphone, circuitry and all, using just metal and plastics as inputs. The ability to mass-produce using 3D printing has long been a holy grail of the field, and the ability to custom manufacture pretty much anything by just fiddling with a computer model would certainly be a game-changer. But 3D printing has so many technological limitations that I still wonder if it will truly take off, most glaringly, 3D printed items tend to not work well out of the printer, and fall apart quickly even if they do, which is a big barrier for mass-production. Ultimately I just wonder if 3D printing will be something more like Supersonic Travel was in the 70s, something that was seen as the mass-market future but was in fact relegated to only specialized roles while more boring “old fashioned” things kept their market share.

The Internet of Things is something I’ve never really gotten the hype for. There are certain applications where having a device always connected to the wifi seems like it could be value added, but most of the hype seems to be marketers trying to see a subscription service for a device that used be be a one-time purchase, or from unrealistic promises that don’t fix the Oracle Problem (ie suppose you give you machine a wifi connection so it can always tell you when certain conditions are met, but will you necessarily trust that your machine is giving you good data or will you have to double check each time anyway, negating the benefits of having the wifi in your machine). Frankly, I don’t want anything in my house to be connected to the wifi unless I expect or need to play Youtube on it.

Another Next Big Thing could be the DNA/protein revolution. The Human Genome Project was a massive success, as was the development of modern Mass spectrometry, and a huge amount of modern biochemistry couldn’t exist without these techniques. Our ability to read the sequence of any protein or piece of DNA we want to, and to alter them in any way we please, have definitely given us a leg up in fighting genetic diseases and engineering proteins for a number of different purposes. In theory, biochemistry can let us create proteins to do just about any job that ordinary chemistry does, only faster and better. This includes highly speculative roles like uranium enrichment and carbon capture to even humdrum every day roles like plastic production. The ability to use genetics and proteomics to both cure our diseases and for industrial purposes is certainly enticing, but I’m still not sure the technology is there or will be there soon. Without getting too jargon-y, proteins can only do their job if they have the correct shape, and our ability to create any shape we want is not fully developed. When you change a single piece of a protein, it can have enormous effects on the protein’s structure and function, and it’s often difficult to even test these effects. Some people have told me that “genes and proteins are the next coding language” but until it’s as easy to test a protein as it is to test a program, I’m not sure that’s true.

Finally, outer space. Will the next trillion dollar company be a space company and not a tech company? I’d love that to be true, but I’m not sure. The best argument I’ve heard for the economic viability of space colonies was actually a really dumb and technical one. If you assume that there is already people living on both the Moon and on Earth, then in theory it is cheaper to ship anything from the Moon to the Earth, versus shipping something from the Earth to the Moon (due to differing gravity and atmospheric drag effects). If we then assume that economies of scale can be harnessed to make producing things on the Moon and producing things on Earth cost almost the same amount, then any company that moves its production from the Earth to the Moon has a comparative advantage that cannot be taken away, and it can service both the population on the Moon and the population on Earth more cheaply. Thus a Moon colony should be (economically) self-sustaining once it reaches a certain size. There are of course a hell of a lot of assumptions with this plan, and some of them are even bad assumptions, but this is genuinely the only compelling argument I’ve heard for colonizing space other than the Tsiolkovsky argument, which isn’t much more of an argument than but I WANT it to happen.

So what is the Next Big Thing? Honestly I don’t know, and I don’t think anyone does at this point. That was one thing I kept thinking about while reading The American Challenge. JJSS and people like him seemed to think that the best way to run a country was to foresee what would be the “Next Big Thing” and then invest in it. But JJSS’s predictions on The Next Big Thing were 1/3 or 1/4 depending on how you wanted to score him, and frankly redirecting national budgets into government projects with all the bureaucratic inertia and election-cycle-thinking that comes with them just seems like a terrible idea. Better to let the free market create a virtuous cycle where the good ideas win and the bad ideas lose, rather than create a government system that can be handcuffed by political or interest-group concerns to throw good money after bad and ignore successes in favor of prestigious failures. I don’t know what the Next Big Thing is, but what do you think? Feel free to comment below.
