modern IDEs are nice on operating systems like windows because they bundle the compiler and text editor and debugger together, and installing and configuring anything on windows is a pain of wizards and menus, especially if you want those programs to talk to each other correctly. I've had jobs where we have spent entire days configuring and installing visual studio and related software and activating all of the licenses and connecting all the databases.
But on linux you can just can just figure it out once and "su install compiler-version text-editor-version debugger-version && cp dotfiles ~/.config"

Nah, the turn of the century IDEs were better enough that almost all the text editors adopted the relevant feature.
We mostly do not have pure text editors like there were back then. There's nano, and notepad++, but on the traditional holdouts, vi became an IDE, and emacs, that was already an IDE turned into a multi-language one too.
That said, those features were compelling enough for every editor to adopt, but didn't change the picture enough so that people had no choice but to use them. It is still perfectly viable to not use the IDE features of your favorite editor.
The impact of the "modern" IDEs of 20 years ago was distinctly measurable, and sensibly perceptible by anyone that tried them.
At the same time, it's not even clear if the gain from LLMs is even positive.
But if your claim was that neither was relevant enough to change the overall noisy productivity of developers, than yeah. At least not positively.
