As for PCs, the vast majority of people use Word, Outlook, and a browser (usually the memory hog Chrome followed by Edge). Again, explain how a PC which is three years old reduces productivity in this day and age.
Easy - all of the added AI/telemetry crap in Windows 11 slows down all of the programs you're trying to run. And it doesn't help when those programs themselves are also being bloated with AI/telemetry.
For the past 25 years, there have always been between 2 and 5 concurrently-supported versions of Windows Desktop:
For the first time ever, there is now exactly ONE supported version of Windows Desktop (excluding the various feature updates, and also excluding the Enterprise LTSC versions because, let's face it, nobody's legitimately running those at home). I'm sure Microsoft is thrilled that they don't have to worry about supporting old desktops anymore (aside from the people paying for up to 3 years of extended support).
In other words, they blue-shifted the image back into the visible spectrum, which I'm sure would do a decent job of counteracting at least some of the extreme red-shift you get from observing such distant objects.
Whether they actually tried to calibrate the blue-shifting (e.g. by looking for emission spectra), I don't know, but I'm sure it wouldn't be out of the question.
I wouldn't say that the MIDI synth in your PC is necessarily a different thing - it's "effectively" the same as a hardware synthesizer in that, if you've got an appropriate adapter hooked up to your computer (whether via USB, RS232, or the old DA15 "gameport" on old soundcards), it can receive MIDI data from other devices and convert into audio to play through your speakers.
I say "effectively" because real MIDI synthesizers probably do way more than the simplistic "Microsoft GS Wavetable Synth" on all Windows installations, but there are other MIDI synths on Windows (such as VirtualMIDISynth) which do a lot more.
What about dog's milk?
"Nothing wrong with dog's milk. Full of goodness, full of vitamins, full of marrowbone jelly. Lasts longer than any other type of milk, dog's milk, (since) no bugger'll drink it. Plus, of course, the advantage of dog's milk is that when it goes off it takes exactly the same as when it's fresh."
Do not simplify the design of a program if a way can be found to make it complex and wonderful.
