IMHO the problem with programming isn't the total stress on the brain, it's that there is very little observable output of all of that effort. I spent some time working with commercial HVAC and some of the problems there were on par with the most difficult technical problems I've worked through in information systems. The difference is that, with HVAC, all of that effort results in an outcome that connects with the limbic system in a way that doubling throughput or halving latency doesn't.
