> 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.
It's an exaggeration. Means that he disagrees with people who blindly repeat something that, on the level Linus operates, is objectively not true.
I have no context on the broader discussion but it seems both sides haven't equalized the plane on which they discuss. In that context I'll agree Linus was a dick.
But, consider what was said upthread: many high-profile open source contributors hear the same crap every day. No matter how gracious you start off, you'll start rolling your eyes and ultimately resort to sarcasm. And some go even further: start insulting. Ask anyone who works in retail.
So again, to me Linus' statement basically uses an exaggeration to illustrate a point: "Stop repeating something as if it's unequivocally true. It's true only in your context (userland application development). It's not true in kernel context."
That people get offended by that says more about them than about Linus.
Finally, I'll agree it can and should be toned down. Not disputing that. But it's also not so difficult to extract out the true point in such a rant and move on.
