But in 2022, this is no longer true. Even the most limited platform you can think of can comfortably run vim. A $5 Raspberry Pi Zero is overkill for vim. And now, labor is more far more expensive than hardware.

It's time to evolve. The reason this page exists, is because vim is unintuitive. But it doesn't have to.
