I totally agree with everything you're saying, there's definitely a long way to go. I am certainly not advocating for going all-in on them any time soon.

I don't see any harm in trying though, or continuing to try and improve them. If we had said that a boom-box sized car phone wasn't useful enough, so why bother trying, where would phones be now?

Besides, you can probably point to any number of people in history that said that humans would never fly, that computers were unwieldy room-sized devices that consumers would never use, that the internet would never be anything more than communication between universities.

It's also just fun to think about the possibilities! :)
