Okay, I personally think AI is in a hype cycle. But there's only one "number" in this discussion and that's Bing's market share.
Now yes, I tried Bing Search AI and sometimes I'm able to get a good result. But honestly? It feels slow, sluggish, laggy. The AI responses are nonsensical as well, the AI in Bing simply merges the top results together into paragraph form... and doesn't always write cohesive paragraphs as a result. (Ex: if information in link#1 contradicts link#2, and then sentences are merged together, you'll get an AI-merged, inconsistent sentence/paragraph on those two subjects).
The AI is impressive at word generation, yes. But is it useful? Jury's out. I find searching "normally" to be faster and more effective. I dunno if I just need more "AI Training" or "AI Whispering" to get Bing AI to work correctly, but ... its not easy to use at all.
