And hot ice cubes are a thing. They've made ice at up to 650K if the wiki phase diagram is any indicator https://en.wikipedia.org/wiki/File:Phase_diagram_of_water.sv...
I'm going to reiterate that you are the one who started calling a CPU an ASIC, I'm was just trying to match your language to be friendly. A CPU is technically as ASIC for a certain class of computable functions, so if you want to call it that I'm happy to as well. If you don't want to call it an ASIC we don't have to, we can just call it a CPU.
> A Monero mining ASIC is called a CPU, by design.
This is true. If you make a Monero mining ASIC, then you have made a shitty CPU. Off-the-shelf CPUs are the best possible chips for mining Monero with, and this is by design.
The Monero hash function works by generating random programs and then running them, so that you need to have a CPU to generate hashes, and all of the optimisations in a CPU benefit Monero hashing. If you build a chip that does this, you have built a CPU. It's even built so that the instruction set is irrelevant, because the same program is run thousands of times before a new one is generated, making the overhead of translating it to any needed instruction set negligible.
