Company has successful products, all done with C. Company has complete
tool-chain - in C. Company has well educated developers - all
specialists for C.

Lets throw all away, we could gain twice the productivity with Ada (the

When did you buy your last car? Did you ask the salesman: "Is the brake
programmed in Ada?" I'm sure, you didn't.

bit hard.

No, it's not called "idiotic", it's called "shareholder value".
