Oversensitive? Is the contractor who chooses a Dewalt or Ridgid over a Ryobi for daily work "caring about irrelevant stuff"? A drill is a drill right? Why is it different for us in software?
But I think the point OP was making is that contractors have a licensing and training program, and if you hire someone to put a roof on your house, they either have to go through that process or work under someone who went through that process. I mean, choosing the right tool is a small part of that, but someone in the chain of command is gonna have words with you if you bring your Xcelite screwdriver and try to use it on the roofing job.
That's not true almost anywhere in software, and that probably makes a big difference.
(I mean, not being educated myself, i personally have mixed feelings about licensure. But it's a good discussion to have, and I think that there should be something like the PE for software engineers (and there was, in texas, but it will be discontinued this year. )
It's impossible to do a perfect job under such conditions, and it's anyway impossible to please everyone.
