I think we are just a bit biased and disconnected from the general user.

You see, the problem is not that the bot is generally useless. It's just that bots are not 'useful' to you in particular (and to most Lemmy users as of today). Most of the people using this particular website are used to reading a lot of technical (and non-technical) stuff and therefore, are generally good at understanding most computer and internet concepts, which is something I cannot say for the general population outside of these circles. Imagine the old lady trying to buy something on the 'interweb' or people who are just not particularly computer literate or 'tech savy'.

In your case, you mention a bot giving you an answer that you yourself were too lazy to look-up. I'm pretty sure lot's of people don't know where to search and/or don't even bother reading/searching answers to their problems.

See? You just read a whole comment from a stranger because you were curious.

Edit: In reality I agree with you, bots are incredibly frustrating and I do not have any evidence to them ever being helpful, I just wanted to entertain a different idea.
