Yes, it’s 20 years ago that Linus Torvalds decided to bring his hobby to the public.
In his first e-mail it’s clear that he didn’t it could get as big as it is today. It’s also funny to see that he stated that his OS ‘probably never will support anything other than AT-harddisks’, because he didn’t have any other harddisks. Now it supports over 9000 harddisks!!! Well, maybe not over 9000, but it supports almost every harddisk.
Congratulations to Linus and the whole Linux community!
