So, this is interesting so far and I'm bookmarking it for the depth of the author's historical knowledge, but saying "horizontal microcode" was the main difference that "no one talks about"...I mean I was told this was the very difference that make RISC distinct from x86 and friends (what I see now were VAX-like archs), the simpler transistor logic without the crazy micro-programs and the pipelining, I thought this was common knowledge. Is there some other context people think of when they talk about RISC that I'm unaware of?

You're absolutely right. I was waiting to see what the big misunderstanding was about RISC, and I actually rolled my eyes when I saw _horizontal microcode_ bolded. It's an implementation detail.
You seem to have read noobermin as saying the opposite of what I read them as saying, because to my eyes the conversation looks like this:

    <noobermin> X is Y
    <baryphonic> You're absolutely right.  X is totally not Y
