Even if you solve the scarring issue, the invasive option seems impractical. They might use it on patients that are locked out or missing senses. But what doctor would let a healthy person get brain surgery so they can use a computer slightly faster? Would the FDA ever approve something like that? However there are other options. People have figured out how to hijack existing senses. There was a plate you could put on your tongue that would let you see images through the nerves on your tongue. There was a project that converted video to sound waves, so you could learn to see through your ears. And there was a guy who made a vibrating suit which could let deaf people hear again by converting sound to more noticeable vibration frequencies. It's unclear what these extra inputs actually add over just presenting information on a computer monitor or HUD and using vision. I think brain interfaces are massively overhyped. Our brain is already super flexible and can learn to process info from existing interfaces just as well.
