That's not much of a contribution to the discussion.
Why not? Building physical things for yourself can be just as satisfying as building virtual things for others.
I mean, I like building things, yes. I make small tables, I replace parts on my car. But I can't really hope to raise a decent house, even if I had 20 of me.
Ok, so you managed to put up a house? Wait, there's more! Did you build it to code for fire, sanitation, earthquakes...? Of course, some of the codes are overly pedantic and there is some baggage there, but frankly I don't expect IT professionals moonlighting as completely untrained architects will build houses that aren't going to crush hundreds of people in earthquakes or start fires.
I can certainly build a shed, even from lumber, and pretty much anyone moderately competent could.
I should have you over to my house sometime. I completely tore out the downstairs of my house. The guy that's helping me with the kitchen cabinets is an old cobol programmer. I think your experience with carpentry and people that enjoy carpentry might leave a little to be desired. (I don't mean any disrespect by this) and I'm not saying that just because you chose "saws and sandpaper" for what is needed to build a structure.
I am curious why do you think tech people would not be interested in building things using lumber? If you are looking for a book to read pickup "Shopclass as Soulcraft." I don't think its going to make you want to pick up a trade but I think it might give you a different perspective.
IMO this falls into the ol' boat of engineers thinking they can do everything just as well as people who were professionally trained. "Drilling for oil? How hard can it be!"
P.S. Unless frames come precut or premade these days, how exactly do you plan to build a house without some form of saw?
Speaking of framing, you know that aisle of 2x4x8s you walk past at home despot? They are not all 96 inches long. If you look close some are labeled "framing studs." They are precut to 92 5/8 precisely so that you don't need to cut down every stud when you are framing a wall.
Well, I'm here to tell you that you're wrong. He won't have to inhabit a shantytown. He'll have a nice storage cell to live in.
