> Yet you can do the same for the OS technology, if this was about something that was implemented on OS Y: “It’s not interesting to me that this was developed on OS Y. The abstract techniques that they used are more interesting to me than the specific OS they used.” I would absolutely say that. OS evangelism is as uninteresting as language evangelism, at least in comparison to a discussion about abstract software techniques / concepts and their implications. > Complaining about evangelism without offering any kind of criticism of what is supposedly being evangelized betrays just as much bias as the supposed missionaries. I did offer clear and actionable criticism. Evangelism is less interesting than a talk based in general first principles. That’s my opinion and I think it’s a widely held one. I never accused the presenters of bias and if they are biased, I have absolutely no problem with that because all humans have biases. For the record, I am not biased against Rust but perhaps I am not sufficiently biased in favor of Rust to the extent that Rust evangelism would be interesting to me.
