A lot of people have been claiming it's 1-2 days away from collapsing for the last three weeks. I haven't noticed any issues since Elon took over. Seems like he trimmed a lot of fat with no apparent consequences to how Twitter runs. I think that's pretty common for large tech companies. Didn't Facebook just lay off like 10,000 employees and no one batted an eye? For the majority of people that use Twitter, if they didn't know Elon bought it, they would have no idea anything is different.
We'll see, a lot of business can run for a couple months with a skeleton crew. But even in that time they've had non stop issues, doesn't bode well.
