Over the last 20 years the economy has become dysfunctional. It no longer really resembles a free market; monopolies have established barriers to entry everywhere. And the biggest investors are awash with helicopter money that's been doled out for favors by the political class.
So those investors have tons of cash to burn and surprisingly few opportunities. Even within Silicon Valley/VC there are surprisingly few who seem to really understand the fundamental economics of software. Or perhaps those economics just aren't that important when you have billions of dollars on hand and cash is obviously not going to get you a return. Any whisper of possible exponential growth is worth throwing money at. Crypto? Why not. AI? Why not. Datacenters? Why not. Tulips? Why not.
This is by all definitions an empire in decline. Everything is broken or fake. Everyone is afraid to do what needs to be done. Power forbids it. So we're all just waiting for the other shoe to drop. Our secret police aren't as bad as the late stage USSR's yet, but hold Uncle Sam's beer...
(That's not a recommendation to try and time the nadir, by the way, as it could easily be 50 years away.)
