> Consumer-grade hardware & software is a wonderful demonstration of why aerospace and medical systems cost what they do.

Can you elaborate on what you mean by this?

[allenrb]

Sure. I’m talking about the general category of “software which must work, else people will die”. The difference between working 99.9% of the time, vs working 100% of the time appears to be very expensive.

Automakers and their suppliers could develop to the same standards but the software and associated hardware might well cost more than the rest of the vehicle. There’s no market for that.

They're not allowed to unpredictably and inexplicably fail like consumer stuff, but they're also orders of magnitude more expensive.

Even with that cost, you usually have to get device-specific training and sometimes certification to operate them. They also often have rigid operating procedures you are required to follow, with deviations possibly leading to fail-safe modes, audit, and/or recertification...
