Windows NT on 600MHz machine opens apps instantly. What happened?

People bring up cruft and lack of optimization, but leave out the user demand for features.

Did notepad and command prompt really get that many more features?

Command prompt (now Terminal)? Yes, tons. A massive amount of new features really.

Notepad? Kind of. Newer UI library so it handles display scaling a lot better. Handles different line endings and encodings much better now. Handles the system UI dark mode. The interface supports tabs.

Can you name a few that could explain the 1,000x performance cost?

Also, have you heard the story about the guy who told MS that their terminal was shit and could be fixed, only to be ridiculed by a fleet of "super elite 500k/year engineers" that in the end turned out to be ... wrong?

Display scaling support

Tabbed interface

Support for command interpreters other than just CMD

Multiple profiles for different interpreters and settings

Support for a much wider range of console control characters and terminal emulations (ssh'ing into linux boxes works really well)

Way better resizing support

Clickable URL detection

More (and customizable) keyboard shortcuts

Support for background images

Support for transparency

Configurations as easy to transfer JSON files

Copying text is a way better experience

Just a few of the features that I use all the time. I can't stand using cmd.exe anymore, its an absolutely miserable experience in comparison.
