As an outsider (haven't used KDE in 15 years) I perceived "Plasma" as just a fancy "very major" version number. The usual post-semver insecurity: "if every change has to be a major increment if it can't be guaranteed to be an unfailing drop-in replacement in every corner case scenario, how do I express a larger change?" Not nice, but far from cringe. But I certainly won't rule or that this is just me enjoying the blessings of ignorance :)

I find it more concerning how the author celebrates all those hypothetical device classes, instead of focusing on being good at one thing (desktops). Feels a bit like being stuck in time loop where Windows 8 is still the hottest new thing (it never was, got ridiculed from the start). But again, I might be wrong, if there are non-desktop use cases that are not only live in production but also major contributors (perhaps something like large TV brands building on/building Plasma for their UI?), then they have made all the right calls.

off topic: feels a bit weird to read through that very talkative YouTube monologue style, that's probably contributing a lot to my perception. But, wow, so much better to have a transcript than the video itself!

Don’t agree. The vast amount of KDE related projects meant that the name described so much more than just a desktop environment.
