My recollection is a couple years before it popped everybody (except tech CEOs going public or investing tens of millions in dog food delivery infrastructure) was in disbelief it hadn't happened yet
i think we're in that (quite long) stage with AI right now where most halfway smart people "know" but they're still invested due to the greater fool theory and still talking their book.
What do I have to lose? I'm just going to get decrepit and die anyway if it doesn't work out.
