Perhaps the fact that Google is keen on Rust internally is part of what Ted Tso does not like about it ( he works for Google ).
Many outside the Rust community see the enthusiasm for Rust as overblown. Perhaps they think that pushing back on Rust to create a brake on this momentum is restoring the balance or something.
One thing I have noticed, when devs push back on inferior languages, they are able to cite all kinds of technical reasons for doing so. When they cannot come up with reasons, perhaps that is evidence that the language is pretty good.
Ted’s rant basically says “we have more code so we matter more and that will be true for a long time”. I agree with the assessment that this kind of blatant tribalism is “non-technical nonsense”.
