Doesn't this still line up with the original point though?

The incumbents had the exact same opportunity to capitalize. Blockbuster could've leaned into streaming hard before Netflix.

I do think that's become a bit harder recently, though, so the original point is slightly less relevant (though obviously still exists, see for example OpenAI vis-a-vis DeepMind). Big companies are much faster on chasing trends, even if they end up amounting to not much. See crypto, for example. I do think part of that reason is because the current wave of companies capitalized where incumbents faltered, so they're desperate not to make the same mistake.
