Interesting, I just don’t get that last line, Linux came out in 1991, so how is 1991 way before Linux?
I’m not sure either, that if the GNU project had managed to make a decent kernel, that it would have made the world a different place today. At least not for the better.
The Linux kernel is the most successful piece of open software ever made, and it’s GPL like GNU. I am far from sure another kernel would have been equally successful either technologically or in benefiting all sorts of computers.
