Again, very sorry you misunderstood me. However, I am now pretty certain one of your difficulties is that you stop short of reading my next sentence, and then my next sentence after that. See my quoted comments above. I made very clear these are strictly my beliefs.
> If you want to know Linus's reasons, the read the LKML.
Perhaps when I said "I believe" I was being too subtle about what "my beliefs" are or what "beliefs" mean.
I hope you would agree -- just because one has expressed certain technical reasons/desires does not mean that there were not any unexpressed social reasons/desires, or what philosophers also call "higher order volitions" (long term volitions, or volitions about volitions), for one's actions.
Now -- I do not know but I do believe there may be social reasons for Rust being adopted in the Linux kernel, because I have read the LKML and I have reasoned about why Linux is experimenting with Rust drivers from things Linus and others have said.
Feel free to disagree, of course, but, in the future, please make more of an effort to avoid mischaracterizing me again.
