There’s no big reason why remapping couldn’t be done in a way that doesn’t require actively running software on the host machine. QMK, the open source firmware for keyboards has had this for years. You can update your keymap with an online editor, but once it’s flashed, your mappings will be remembered regardless of which computer/phone/whatever you use the keyboard with - without having to run any software besides the OS on the host.

Dumbest shit I’ve heard this week.

Switches that last forever would be interesting. Subscription models and sw updates for a mouse are the very opposite of interesting. I’d pay not to have either.
