You and him are incorrigible. Him for the naive assumption and stereotype that “techies” don’t do any manual trades or crafts, you for looking at the count of activity on stack fucking overflow for woodworking.
If you have better data that shows an overlap between those in the technical field and those that do woodworking with highly specialized tools, I'm all ears; I'm willing to be convinced otherwise.
In the meantime, here's another anecdote for you - I do woodworking (and gardening and constructions) and I don't own a belt sander.
