Do you think Bing has a chance to challenge Google?

I don’t think Bing is very userfriendly. Google is more intuitive in my view

No

I've started using Bing's implementation of chat. I'm a search power user, and I'm convinced that if Google doesn't come up with something in the same league it can loose half of it's share of the market.

the promise of a functional AI is real, that's all we basically know. It will be integrated in to Google and every other product we use. Every tool we use, like maps, emails and film recommendations will become better, on all platforms. Best example is - when iPhone came around, it didn't replace phones, but it pushed/established the culture of smart phones.
