No, it is not that bad. It's actually very nice.
It affords a lot of consistency, is relatively easy to understand (once you're familiar with the convention), and theming allows you to modify all the colors and sizing in one file rather than modifying a lot of CSS
I think the worst that can be said about it is that it is unnecessary, but I cannot see a true downside to using it besides personal preference. It gets the job done efficiently and correctly and that's what's important at the end of the day
I think the voting ratio pretty well demonstrates one obvious hurdle: people don't like it.
Even people who are happy with AI seem repulsed by the idea of it replacing human intimacy. So unless you have some real ride or die friend and family, you'll have to risk judgment from them or keep it a secret
There's also the fact that right now most AI bots are toadies by nature - meaning they will rarely disagree with you and will generally capitulate to your will. That would be off-putting for some, including myself.
They also (currently) don't have great memory and will not always recall things that are important to you. No matter hpw any times you tell them.
Obviously, there are larger issues to consider, but if you're already considering the leap then you may not necessarily be convinced by arguments about humanity and what's natural.
