So "X" - nothing to see here. Elon's in control - Part XXX

I think you're debating from a slightly unrealistic level of expectations WRT Tech Debt and that giant umbrella of "Making Code Better". Not everything's a question of competency, rather than of compromise and what's possible within the given timeframe, budget or priority. There's clearly a problem going on a Twitter, but it's doubtful it's a single point of failure - though thanks to Musk's idiot management with the arbitrary firings these problems are ultimately going to get worse as developers (presumably) multitask their ownerships.

TBH from the dev's comments it sounds like the ball is being dropped at the server level 'cos as I said, there's only so much an interface can do while it waits for slow servers to respond. I'd be slow to "blame" the Android team when it's clear they know the problem is happening at a point they can't contribute.

Ok, we need to stick one field here to try to make it easier to rationalise: if we stick to Senior Engineers, then what do you expect them to do beyond constantly asking for the time and runway to fix things? I don't think you can fairly call him part of the problem when for all we know he brings up these issues every single Retrospective Meeting. Aside from anything else, it's not necessarily a Senior Engineer's job to plan or influence decision-making - not sure where you work but seniors tend to only have very limited power there. They can suggest, but rarely influence - especially in a corporate environment.

There are undoubtedly bad developers - again, worked with them plenty of times and they're not always aware of their badness - but a top-down structure tends to ensure that if there's a rot, it starts at the summit - not in the trenches.

Ah here. People have bills and mortgages to pay; a family to feed; I dunno, a drug habit to maintain. If you're now gonna attack how long he worked there for, we're on a hiding to nothing and does start to seem like you're determined to just blame him for something. It's not Auschwitz we're discussing, his very presence doesn't make him culpable for the sins of the app. Sins, I might add, we're both presuming and spitballing about.here

Maybe he was happy to just coast along and not think the app was that bad ... ... until of course some colossal díckhead started trash-talking his work in public like he's ... well, incompetent. I can understand why someone's dander might rise if their ostensible boss started dumping on their work - from a point of technical ignorance n' all. One thing to work within the constraints of the system - another to have the system then shít on you.

The way Musk is revealing his tech obsolescence, I expect him to next declare Twitter was going back to HTML4 support only, cos everything afterwards was bloat and affectation.

Mind you, his fans would probably applaud that too, reckon Netscape's death was a liberal conspiracy.
