For me, the issue isn't that I'm unwilling to learn new things. It's that I cannot use these keybindings anywhere else. Almost all online editors and workstations have some sort of vim keybindings. When I ssh into a Linux machine I can trust it has vim editor. It's like qwerty keyboard, I'm sure that there's better layouts but I just cannot discard the flexibility of being able to jump on most machines and be 99% productive almost instantly.
