I'm not sure what artemis or orion are, but you can blame defense contractors for this. Nobody ever got fired for hiring IBM or Lockheed, even if they deliver unimpressive results at massive cost.

Put a 4 nm CPU into something that goes to space and see how long it would take to fail.
One of the tradeoffs of radiation hardening is increased transistor size.
Cost-wise it also makes sense - it’s a specialized, certified and low-volume part.
I don't disagree that the engineering can be justified. But you don't need custom hardware to achieve radiation hardening, much less hiring fucking IBM.
And to be clear, I love power chips. I remain very bullish about the architecture. But as a taxpayer reading this shit just pisses me off. Pork-fat designed to look pro-humanity.

It's an IBM designed processor, what are you talking about?!
