I take your point that it's _more_ helpful than guitar, but I see it like this: I need 100 relevant-ability-points to build a dishwasher. Playing guitar gives me 1. Knowing how to program gives me 10. I'm still 89 points short.

I just think it's weird how we think that being software engineers translates in some particularly helpful way to building a dishwasher, when really one would need a multitude of skills to do so - involving electrical engineering, mechanical engineering, fabrication expertise, materials engineering.
