Why didn't those artifacts/relics survive into the modern era?

There's also something about the early 00s that made software developers go crazy in Java land that they decided to over engineer software for no real benefit and come up with overly complex architectures that don't really address the core issues but rather imagined issues that turn out to not be that important in practice.

They did survive, Qt, VCL, FireMonkey, POCO, but the dark energy of the Electron force it too mighty.

Also in the 2010's we had the rise of scripting languages, thus we have a whole generation that never used compiled languages and are now re-discovering systems programming via Rust, Zig and co.

A history lesson, before OOP, there was Yourdon Structured Method, and plenty of C enterprise architects jumped into it.

The GoF book used Smalltalk and C++, predating Java by a couple of years.

The Booch Method used C++, and predates Java for a decade.

Ah and there was that whole operating system written in an OOP C dialect, including its drivers, NeXTSTEP, which also survives to this day, with more consumer deployments than the Year of Desktop Linux.
