Seems the only impossible problems that can't be solved by AI are things that make metrics falsely look good to investors

Ironically X shouldn't care about those metrics, it's privately owned by the world's richest person...

It's privately owned, but by a number of parties all with a lot of money on the line. That person may have pulled together the investors, but it most definitely has investors that it needs to answer to in the medium term. In the long term, they have stated that re-floating is a goal.

The valuation of the company matters to the banks and VCs who own X.

And the primary way to evaluate the worth of a social network is user engagement metrics.

Source, substantiation?

This is a good one, another one that blows my mind: when I use the "I'm not interested in this topic" button and refresh the page, it shows that very same post at the top of my feed?!

I had to resort to configuring "muted words" to actually fix the problem.

Its very weird to me that such basic things seem so bugged on a platform that popular, but other much much more complex things (mass video streaming, Grok itself) work totally fine?!

Idk. Ask it if you should close your account and see if it gives an honest answer.
