This sounds like a humble brag to stroke your own ego
The work I do on software I consider as relatively intelligible, but the woodwork I do, requires as much of my brain as the programming, just in a whole other area of my brain.
Your harsh judgement on the matter is just rather irrelevant, it works for him, it tickles his brain, and was just an honest response on github, no need to get trolled here on HN.
If you read my initial comment carefully you’ll see that I’ve made no such conclusion.
