If anything the pessimists are being proven right.
The point is both are disconnected from reality. What we need are people that aren't full of shit. There is a place between "everything is impossible" and "everything is possible" that works better for getting things done.
Exactly, and we know for sure that Boom are definitely NOT in that place, how?
It's only been a decade, they're only behind by an order of magnitude on their timeline, and they don't even have a concept of a plan for the critical component. It's fine.
Now let us chant the HN pessimists rejoinder in unison.
LLMs are a fad. Bitcoin is a fad. Saas is a fad. Dropbox will never work as it can be trivially replicated on Linux using FTP, curlftpfs, and SVN...
Pessimists get the warm satisfaction of knowing their choice to not try anything interesting and never take risks in life was correct…most of the time. They cheer on failure from the sidelines so as not to suffer the ego-death of comparison.
Optimists…as the saying goes…they don’t get to be right most of the time. But they do get rich.
But hard things have been done before. Throwing rocks at the people trying doesn't do much to help them. They're fully aware of the reasons they might fail.
Would you rather these folks just not try at all, so you don't have to feel jealous if they actually succeed?
