Sure you can, if it runs/functions properly, it can be reversed. Physics is physics is physics
is math, which is expressable in computable models most of the time.
Not that hardware manufacturing industry is this homogenous body that moves all at once, especially when TC(Trusted Computing) has gotten so much bad press. I wouldn't even mind TC if the hardware's owner (PC user) had the option of controlling all the crypto keys, thus still retaining full control of his hardware and attaining the actual security that TC aimed to achieve. TC without such control would be just selfish DRM from manufacturers (who don't actually care about such things, despite what you might think), and more hidden hands that try to push them to commit such evils (content industry, among others).
tl;dr: Oh yes, you can reverse anything if you have the resources and time to do it. No, your doomsday is unlikely to happen since the industry cares more about profits from their buyers than they care about silly conspiracies.
