> I remember the 90s and the 20s, when everything happened locally on the local hardware

I think there's a bit of rose tinted glasses here. You could literally see windows and icons being drawn on the screen in the 90s. Even text UI were slow to draw on screen. We have it good today.

Regarding keyboard shortcuts we are good too. I barely use a mouse nowadays. I use Vimium for Chrome to "click" on elements in pages, i3 keyboard shortcuts to jump to specific applications or workspaces, and the mouse emulator on my keyboard (olkb) to click or use the scrollwheel on the odd thing that doesn't want to work with a keyboard. Luckily many programs have adopted the command palete (most editors, vscode, gimp, etc) so it's easy to quickly invoke commands without memorizing arcane shortcuts.
