If you want to have a conversation with me about the things I'm talking about, I welcome it, but I don't see that happening.
Yes, like I keep saying: two clusters each within an order of magnitude, separated by three orders of magnitude feel to me like two distinct things. That does not at all feel arbitrary. I think that claim is pretty self-explanatory. You appear to think it reduces to "because I feel it so" and in some sense it does. I am applying my own judgement and values in constructing those clusters. Someone who felt that any amount of memory safety was unacceptable would structure them differently. Someone who cared naught about memory safety would similarly group them differently too.
