This is under-appreciated part of it. Search had been deliberately degraded for some time now as part of the usual enshittification arc. Where as AI is still in the early part of the arc where its trying to do better, so the difference between them seems even bigger.
But seeing disney+ now go all ads for all tiers just shows that's the way they arc bends. Eventually AI will take over and when it does, it will then turn into the shittiest shit ad-infused service the world has ever known.
