Imagine thinking you can judge anything about a developer (especially Senior/Staffs) from screenshots of code. Elon has truly lost the plot.
There is a huge back end on Twitter even though the front end looks poorly thought out and over-simplified... The back-end reporting and tracking apparatuses built into that site are probably failing miserably, and pissing off a lot of undisclosed clients. Elon needs technical architects and technical direction more than just developers if you ask me. I don't think Twitter will completely fail, but I'm pretty sure it…
I don't think the majority opinion on engineers is that it'll crash and then they'll throw in the towel and that's it, but there's plenty of other ultimately fatal outcomes for twitter, and plenty of non-fatal technical issues they can encounter on the way there.
