Considering the crypto itself does not produce anything of value I´d be surprised if it would continue to outperform the stock market as crypto starts to stabilise. Maybe it could be used to be a little more resistant to inflation than with regular cash, but wouldn´t make any sense to me if the value of crypto would consistently grow to a bigger percentage of all wealth on earth.
Crypto is a technology just like Microsoft Windows is. As more people use it its value increases. Only difference is now there is no bill gates and the rewards are shared by all early adopters.
No one is forcing them to retire, I for one would be interested to see what these productive people would come up with when they shift their goal from making a great profit to making a great social impact.
I'd be willing to bet that at least some of them would. Instinctively I would also guess that it would lead to a better outcome on average, but as I'm less certain about that which is why I would like to see it tested out.
True, though I do think great profit is not possible with _maximal_ social impact (unless hoarding cash serves to restrict total consumption and thus limit climate impact).
And the light pollution on its own is a concern - why the everloving fuck should Musk of all people get to block humanity's starlight for his own private profit.
I sincerely hope this ages better than the comments rejecting the initial announcement of Dropbox saying no one will need it. I'm afraid that Facebooks best bet to grow even bigger is to try and force themselves in the aspects of our life that are now still mostly "offline". Facebook doesn't have to get everything right from the start it just has to be able to use its resources to outpace the competition.
Could burning biofuel to generate highly concentrated co2 cheapen the process? This way there would also always be energy available for the capturing process and the capturing plants would be mostly just plots of land with plants on them.
