Keep in mind that what's written is mostly opinion. Very few people know the working of Twitter's IT infrastructure so it's mostly all guesses. Even if there are people that truly know what they are talking about their comments get drowned out by all the people that want to give their opinion.
We used to see the twitter whale a lot in the past but not lately. That hints to the idea that they have harden the infrastructure to tolerate common problems. Given the past problems with these social media companies that were related to a one point of failure that brought down the whole network. I suspect that it takes a lot to bring down the whole system at once.
There won't be any collapse. The remaining engineers are leveling up and understanding what they need to know. My experience has been that if I don't know a system, I can get familiar enough with it within weeks. If for some reason I can't figure out a part then I treat it as a black box and work towards replacing it. If the remaining engineers can't do the same then it's time to get a leader that can help them thru the situation. All these tech companies have spent top dollar to hire the best so they can get thru the knowledge loss relatively soon. There's plenty of brain power left at twitter to get them through the current problems.
