If engineering and university labs show up they will probably have a lot they can pick up from the people with PID grease and prop dust under their finger nails... not to be one sided though, as technical engineering and backyard/shadetree necessity and ingenuity would seem to be more synergistic in combination than just one or the other, which reminds me that if everyone can be allowed to sustainably contribute what they are able to, then everyone can or will benefit, but if they can't, then we won't... "or something... uhhh... huh huh... yeah... uhh... huh huh... yeah..."
