I often find it amusing to read Ken Thompson’s ‘Turing Award Lecture’, where he reflects:
The moral is obvious. You can’t trust code that you did not totally create yourself. (Especially code from companies that employ people like me.) No amount of source-level verification or scrutiny will protect you from using untrusted code.
The rest of the lecture is well worth a read. This appeared in Communications of the ACM, August 1984 … (and has been quoted here before) - only 35 years or so ago …
