Exactly that. There was a very nice talk by Warren Buffett explaining that to business leaders at the height of the dot-com bubble - if I remember correctly it's full text is the introduction to his biography 'The Snowball: Warren Buffett and the Business of Life'.

Airlines are a great example - they are everywhere, nobody can imagine life without them, and yet they are yet to make any money ! Maybe they will figure it out before oil runs out on planet Earth.

As for Buffett speach - ther is a specific quote about airlines in it: "If a capitalist had been present at Kitty Hawk back in the early 1900s he should’ve shot Orville Wright"

They make no money because competition has essentially turned them into commodities. There is no differentiation thus no producer or consumer surplus.

[Rury]

Yes about commodities, but what you said about surplus is actually wrong. Consumer surplus is at a maximum when there is no differentiation. That is because when producers struggle to differentiate amongst competition, they must compete fiercely on price, so customers often pay far less than their maximum willingness to pay.

And arguably your own statement here doesn't help the view that the industry is not a bubble, as one could argue most LLM models are not substantially different from each other, and most products integrating them are offering similar features. The industry may need to do better at differentiating if it wants to avoid being commodified.
