| I'd say it's something that has to grow exponentially for a very long time. That rules something like finance out, which compounds very poorly, and hasn't produced trillionaires despite being around for centuries. I'd bet on education. Colleges and universities can be worth billions each. While the billion dollar ones are pretty good, the sub billion ones aren't and are getting competed with by several month courses. It seems something mostly neglected. Universities hire the smartest people, but teaching still uses the same old lecturing technique for decades, despite all this interactive technology. We've learned a lot about psychology and productivity. We have tried improving education technology, but it seems to just be a side gimmick. This can also be combined with upcoming new tech like AI to work better. It seems like something that compounds very well. If you can hack your brain to have, say, 90% comprehension, and comprehend harder things, you can also discover better education techniques and train others. Energy would be second. Oil has already produced trillionaire families, but it's too big to concentrate on one person. I'd imagine Bill Gates's shiny new nuclear plants could push him into trillionaire territory. Combined with the new electrical vehicle trend, people could be migrating from oil to electricity. |
