Now that we are out of the Cambrian explosion of computing hardware - are drivers such a concern anymore? Is there any chance we start consolidating on a few core interfaces?

I know nothing of hardware, but as far as I know, my keyboard and mouse work everywhere because there is a formal specification on how human interface devices are supposed to operate.

There are probably good (and anti-competitive) reasons for why hardware still needs bespoke drivers, but from the outside, it seems like something we could address. I have no interest in loading your artisanally crafted Wifi driver.
