@EricLawton @nf3xn @rrwo @szescstopni @Threadbane this is a very interesting insight.

I studied computer engineering two decades later, we were told that SQL had been around since 1974, and most of us assumed that Codd came down the Mount Sinai with the foundations of relational algebra set in stone, and everybody embraced it immediately.

Working on some legacy systems at the beginning of my career, I actually also noticed that DB2 and friends weren't fully embraced until at least the second half of the 1980s.

Same goes for C++ - most of the post-2000 students assumed that after Stroustrup's initial draft C++ and its object oriented paradigm came as a tidal wave on software development, but later on I noticed that most of the software up to at least mid-1990s was still written in earlier languages.
