Short term tariffs can allow domestic manufacturing to reach the design and scale to be competitive without tariffs. This was, in theory, the idea behind the 100% tariffs on Chinese EVs. Of course, none of the American auto manufacturers are doing anything with that leeway other than continuing to be terrible.

Look, AI is dumb, and probably not a good thing to integrate into a browser. But if it turns out to be an important thing in the future, then not integrating it right now would be worse than having it.

There’s a measurable fixed cost to adding AI features. There’s room for potentially infinite losses (i.e. entire loss of market share) if they don’t have AI features and need them. The calculus on this decision is pretty lopsided towards integrating AI, even if everyone thinks it’s likely to be unnecessary.
