You should better read what the blind community thinks about it instead of making blanket assumptions.

Also I’m not saying that’s a good thing. It’s just an inevitable thing.

It’s not, listen to the blind community instead of making assumptions (I mentioned that in my first comment).

Because good alt text needs a lot of context, so it must be done by humans for humans at our current state of tech,

Because good alt text needs to be highly context dependant, so you can’t automate it. The better alternatives we have right now are crowd-sourced alt text sites, where volunteers may generate descriptions.

No, that’s not useful at all, but Mozilla refused to listen to the blind community.
