Agree. Tesla pulls off impressive feats on lean staffing.
I wouldn't bet against Elon.
Big difference - Twitter's current lean staffing doesn't have the institutional knowledge, while Tesla's employees were able to build up the knowledge (and pass it along).
I'll try an analogy:
Imagine Dan/JJ decide to suddenly retire 1 day and pass DDMS to MendelRandom without passing him any of the knowledge. Not to disparage MendelRandom, but DDMS would never be the same. This is Twitter now.
However, imagine MendelRandom decided to start MRDMS 15 years ago and build it up organically. This is Tesla.
