I don't think it's really doom and gloom, that's mostly on here.
The normies are all still excited/scared and the valuation based on secondary trading is going up and up.
Maybe not quite as crazy as the dot com boom but I'd say the current environment for AI and related equities is a lot closer to the mid/late 90s than 2004
Normies are on fire for SpaceX, where the economics are horrible and the hype is off the charts.
Normies have never heard of Anthropic, where the economics are incredible and doom vibes are pervasive.
I think both have a similar amount of people who know about it. But it might just be my circle which is mostly in finance and some in engineering/medicine. These are also the type of people who actually invest. There's little doom vibes among those who're older if anything they're the one who think we'll get to some agi type situation.
