I wouldn’t say best of ”good enough” .Tesla is actually one of the worst in terms of ”normal” car quality, even when compared to non-luxury cars. It has great battery, electric motors and even software, but normal items which you can see in normal car, are in the lowest side on quality. Also the way how you feel the car when driving is critized being B quality when compared for example German cars.
In many countries it has been listed on the best place on fault statistics (have most of then)
When you buy Tesla, you invest on EV research, not so much for luxury car while it might drive itself. You get a glance for the future.
Teslas, especially during the initial production runs for any given model, are built like Wayfair furniture. Good enough to do the job, but without a high level of quality. Turns out consumers will accept that.
Returning to the Twitter question: gosh, I hope Elon decides to invest heavily in areas I care about and doesn't ignore aspects which I think are vitally important.

I also think it's worth noting that he brought the best of current "good enough" manufacturing practices to luxury automobiles. I think this is the fairest examination of that, since it includes Elon himself: https://jalopnik.com/best-of-2021-in-epically-nerdy-intervie...
Our expectation around cars is that the build quality will be good from day one; this kind of incremental improvement approach is not common. IMHO it's also sub-par and somewhat dangerous for something as deadly as a car, but that's probably a side point for the current discussion.
We also see this with the Hyperloop. Big optimism, and the first actual implementation in Vegas kind of sucks. Maybe it'll improve over time, maybe not, but there's certainly an initial quality gap.
The question I'd ask is what does the equivalent look like for Twitter? I sort of think the "do it crappy, see how to improve it later" policy is more typical for social media.
