What y'all are forgetting is that when it comes to dominating a technology space, historically, it's not proving the better product, is providing the cheapest/widest available product. With the goal being to capture enough of the market to get and retain that dominant position. Nobody knows what the threshold is for that until years later when the dust has settled.
So from Google's perspective if a new or current rival is going to get there first, then just push it out and fix it live. What are people going to do? Switch to Bing?
So is you want Google to stop doing this dumb broken LLM shite, use the network effect against them. Switch to a different search provider and browser and encourage all of your friends and family to do so as well.
