Re: Bad design and bad project management vs the accountants....

I believe early aircraft software was so "unsophisticated" that Airbus used to use hardened 6809s in the CPUs. The approach outlined was practical for things with 64k of RAM. The mil systems I worked on used several 9989 CPUs, 16 bit with 32k addressable words. They were still complicated enough.

I do question whether with the level of complexity we are reaching it's actually possible to be sure what is going on. The sidechannel attacks on x86 CPUs suggests that there could be vulnerabilities introduced simply by having the wrong functions running in parallel at the wrong time.
