It's a false dichotomy to say you either have to be "all-inclusive to the entire world of developers" or you should applaud project leaders throwing out useless condescending rants with no real technical content like:
And the *reality* is that there are no absolute guarantees. Ever. The "Rust is safe" is not some kind of absolute guarantee of code safety. Never has been. Anybody who believes that should probably re-take their kindergarten year, and stop believing in the Easter bunny and Santa Claus.
What's going on here is not "woke people" trying to protect every little snowflake's feelings, rather it's noting the ranter is making himself feel good at others' expense with no other value added. His rants are completely superfluous to the substantive technical dialogue.
