We aren’t there yet, but we are approaching the day when substantially everyone with the capability of rebalancing a red/black tree on a whiteboard and an inclination to program is either programming or in some other way connected to the function. If a yet higher level of mathematical ability and knowledge becomes necessary, shortages are going to become even more acute. That’s good for some of us but bad for the world. The world would be better off if we could figure out a way to lower that bar, not raise it.
