> “smuggle the exponentiality” somewhere that isn’t being explicitly considered, exactly like all proposals for perpetual-motion machines smuggle the entropy increase somewhere that isn’t being explicitly considered.

this is the gist of this. so he is saying that the scalability issues they will run into, come from the entropy increasing with the N such that heat is the real problem? (ah, so maybe this is also why Quantum computers are usually frozen???)

also, how big of an N are we talking about?

I see a weird echo here, I am thinking about exporting the waste (heat, byproducts, the specific 'how-to? by which, in a way, the entropy rules get 'enforced') as being the problem.

so then, he wrote:

I find this analogy quite cutting... with sharp enough steel and enough acceptance (regardless of how the acceptance comes about.... ok), the heat/entropy can get forced around? time to go get my tin foil shield,

then again, I have only been trying to understand exponentiation ever since I found out it existed, and I had not even heard about the "extended" version of the church-turing thesis, hence I'm some kind of ignorant crank (sorry if this comes across as bitter, but I am studying a master's degree in theory of computer science and I had not ever heard about an extended version of that famous thesis;l surely my own fault for not going to study to the USA or europe)
