Here’s how I see things. I’d like your thoughts:

If those butterfly keys from the 2015 macbooks had been more reliable and more sturdy, they’d be the best keys ever made for typing.

Mouse buttons are the apex of ergonomics, speed, ease of use, comfort, and efficiency. No one has ever put cherry MX brown mechanical keyboard switches on a mouse, and for good reason. Apple’s butterfly keyboard is basically a bunch of little mouse buttons, and they allow for a very ergonomic and efficient typing experience.

The only reason to use keys with 4mm travel is if you have too much muscle memory with old-fashioned keyboards (and to be clear, there’s nothing wrong with that. Do what works for you, whether that’s using scissor switches or using your grandpa’s rusty typewriter). But aside from personal habits, the most objectively ergonomic option (and for most new users, the most pleasant option) seems like it should be a key that balances the most tactile feedback possible, with as little excess pressure and travel as possible, in the most sturdy package possible.

So I don’t get why no keyboard makers seem to be striving for this goal?

Again, that’s just how I’m seeing it. Any constructive points about this are welcome. Peace!
