When do you think the technology will be viable? My guess is at best around year 2070 but more realistically after 2100 assuming the current technological pace.
Guessing any number is silly. Nobody knows. There could be a breakthrough tomorrow, a year, 5 years, 10, 20, 50, 100, 200 years from now. Anybody who pretends to be some authority on this and gives you a rough estimate for when we can expect new technologies has no fucking clue (yeah, I'm looking at you, Ray Kurzweil).
If you look at the history of technological innovation it's mostly been a few males that have been responsible for the vast majority of developing and commercializing it. With hyperloop, tesla and SpaceX Musk is like the modern day prominent innovator in a way that people like J.P. Morgan were in the past with railroads and industry.
Give me a 100 billion dollars and I can do some pretty amazing things, too. We're giving too much credit to the money and not the true brains behind the innovations. Some people argue that the brains only come together
because of the money. I suppose this is a fair point. I just hate how the average fucking person gives credit to Elon Musk for the construction of the reusable rocket. A group of 20 odd year old stoners could have come up with the idea of a reusable rocket. The guy just throws money at it, gets briefed by his researchers and engineers, then hits them with ideas that are more like boss' orders. If it sounds like I'm salty that people are praising him too much, that's because I am, and for the reason I mentioned.
The true geniuses get drowned out in history and get sexy compensation packages instead. This is why I fucking hate being a corporate drone. If I come up with a brilliant algorithm and incorporate it into the software that the company I work for sells or uses, I can't really take the credit. I might get a fat bonus and a big raise, but
FUCK THAT SHIT. I'd have to write a paper and publish my findings in some computer science journal to get any real credit, and that's only if I have a PhD.
