I think you missed that I'm comparing a single company to the entire market crash in 2000.
What about OpenAI, Anthropic, xAI and the other foundation labs that have collectively raised trillions?
What Microsoft, Amazon, Google, and Meta, which would likely survive but maybe lose up to a trillion each in valuation?
What about the very long tail of venture-backed AI companies that will go bust? You might complain that the dotcom number was just public companies, but back in 2000 everything was a public company. A company with thousands of high-earning employees going bust matters to the greater economy whether or not it is Nasdaq listed or not.
If a single company represents the entire dollar amount of the dotcom bust, or half when inflation-adjusted, and that valuation is entirely predicated on that growth continuing at historically unprecedented rates.. yeah we're in a bubble, and the damage when it bursts is going to be big.
That was the point I was making, and I fail to see how forward earnings to share-price ratios has any relevance here. The whole point of a bubble popping is that the market suddenly finds out those forward revenues were a mirage, a house of cards, and are very much made up.
> fail to see how forward earnings to share-price ratios has any relevance here.
the relevance is that these earnings expectations are lower than when the dotcom bubble happened.
The fact that a single company can have a market cap today that is greater than the losses from the dotcom bust is irrelevant. We have more wealth today than back in 2000, and these market caps reflect that.

cant find the forward earnings chart, but PE is close proximation

The dotcom bubble peaked at around 46, while we are currently at 30. Will it grow? Who knows. But the bubble certainly isn't as big as claimed by the grandparent comment.
PE ratio spikes are a lagging indicator though. The spikes are after recessions.
Markets collapse, investments slow/stop, orders dry up, suddenly stocks must be valued on future hypothetical orders post-recession (same company, eventually the economy will turn and someone will buy), current PE values spike as current earnings become decoupled from stock price
