How do you stay alive when there's a billion AI email companies out there?

I wonder how this is not a tarpit idea that YC famously ask founders to avoid.

In that case do NOT go to the YC list for Summer 2025 and do NOT Ctrl+F for "AI"

I must have interviewed for at least 4 or 5 of those companies the last couple times I changed jobs. A few of them were YC. I can't find their online presence anymore, or they have pivoted to something else.
