The "640k should be enough for anyone" quote (even if Gates didn't exactly say it) is making the point is that _right now_ we have no idea about what our future needs and capabilities will be, we can't imagine what "should be enough" will be

640k was enough ... in 1981 ... almost fifty years later is 50,000 lower than a standard off the shelf PC now

If that’s the case I still don’t get it. 640k was enough in 1981, same as how 150 (or 9k) tok/sec would suffice for 2026

The comment seems like the nerd equivalent of 6 7
