Technology often starts out expensive and enthusiast only, but if Intel keeps throwing these wild punches in every direction, why wouldn't we see a steady migration to alternatives? AMD is definitely benefiting from Intel's recent decisions, I am sure Raptor is also starting to get more business. A few more years of shady Intel decisions combined with sufficient negative press and I am sure the market will gladly decide. There are surely plenty of large corporations who can afford the costs and would prefer being able to audit everything themselves. This seems like the perfect storm for competition to finally have a chance.
You cannot deliver competitive quality, performance and pricing right away, completely agree. But there's generally a threshold to how much more expensive it can be in the beginning, and more importantly, how much you benefit from it. The problem here is that only few people even understand the problems with what Intel does, and even fewer people care. My games still run fine so why should I care? HN is a real echo chamber in cases like this and easily give a false impression. As you also mentioned, AMD is the only realistic winner from all this, since it's also x86 so you can switch over and everything stays the same. But in general, remember that people are very good at forgetting, and at just accepting that "everything's fucked up" is the new normal. Intel only needs to keep delivering competitive performance and people will keep buying.
I'd really love to see a big shift to a new architecture, RISC V, OpenPOWER etc. get me really excited because as a nerd new technology in general is always interesting, but the above simply is my prediction of the future based on history. I mean, how long ago have the first serious Intel ME vulnerabilities been disclosed? What happened apart from a short shitstorm on tech websites and some small companies offering laptops with crippled down IME that only complete neck beards care about?
