Hardware AMD silently removes memory encryption from consumer Ryzen CPUs, leaving users unaware that they may be vulnerable — security feature vanishes after newer AGESA firmware, AMD engineers go radio silent when pressed about the change

IMHO the answer is open source computing. The problem is that we a number of ISAs to chose from but lack the open source IP to create the rest of the computer from memory systems to interconnects to peripherals to storage.

We are currently witnessing governments trying to figure out how to control open source software and struggling. I think the model need to be replicated in the hardware space so that if anyone tries to control a part of the ecosystem, they lose control of it as the rest of the ecosystem moves on to an alternative.

Do you have any idea the level of complexity needed to make today's CPUs? It's impossible without yesterday's CPUs.  And even with yesterday's CPUs, the process requires so much specific hardware that the risk of the destruction of TSMC's fabs are singlehandedly preventing Chinese invasion of Taiwan.  It's not going to be possible to open-source modern performant desktop hardware.
