I don't hope that it fails. I just don't trust them with new services because they have a bad history of killing everything that's not generating billions. So probably I won't even bother using it, unless it blows ChatGPT out of the water.
I, too, am very skeptical investing into Google's new products these days for the same reasons.
That being said: I'd use Bard if it was cheaper or better than ChatGPT for one simple reason: These "Chat AI" services are transient. Meaning I ask a question, I get an immediate answer, and there is no long term saved state. So if I used Bard, then Bard got KilledByGoogle, I'm not "out" any built up capital (time, training, cost, etc).
But from everything I've read Google is panicking and embarrassing themselves. Half-baked press conferences, half-baked blog posts, half-baked product launches. Nobody who has got into Bard is saying it is a ChatGPT competitor, and even Google's own launch blog they admit it has limits on two-way conversation depth (unlike ChatGPT).
Google's problem is not the technology, it's the business model. If they integrate something like ChatGPT in search it could kill their entire AdWords business. How many ads can you stuff in an answer? And how do you decide which ad goes to a subjective question? Until they figure out how to monetize an embedded AI in a big way there's no chance they'll produce something useful.
