The computer keyboard is like the US Government - it worked fine when it was introduced, and now it is woefully ineffective because it hasn't recognized that a lot of things have changed.
If 30 years ago, they had replaced the F1-F12 buttons with three big buttons for "Copy", "Paste", and "Switch" (Alt+Tab), we would have flying cars by now. (JK the benefits of all of that productivity would have gone to the rich and Bezos would be a trillionaire, but it's nice to imagine a world where both keyboards and the US Government had evolved.)
Setting up personalized keyboard shortcuts and macros somehow has not become an intuitive, easy to use, integrated part of the OS that almost everyone does. You don't have a set of preconfigured keyboard profiles stored in the cloud that you can use on any computer just by logging in.
The whole numpad area should be replaced with a column of 4u LED buttons whose text functionality can be set manually by users and developers. We still don't have a set of buttons that just are shortcuts to the most commonly used functionalities of whatever application you're using. We could have AI do this! It wouldn't even be that hard! Most of my code gets written by Github Copilot now, all I do is hit tab, but god forbid I accidentally open VIM, I have to remember the sequence of characters required to close it? Remote controls for smart tv's now have voice recognition, and yet the functionality of keyboards hasn't improved at all.
