Ehmm ... do you think all airplane programmers are CS graduates? They are not. At least not at SAAB. Actually, very few are CS. Most are mechanic, electric and fluid engineers.

In at least Sweden's machine industry programming is just something you learn in your engineering role by osmosis and revulations from God, and typically one to three 7 week courses at university.

Volvo Cars, Volvo Trucks, Scania, SAAB etc.
