Re: An electromagnetism paradox

Now put an electromagnet in a magnetic field and it clearly gains energy from the magnetic field. I don’t follow. By “gains energy” you mean a current is induced in the electromagnet? Well, for that to happen, either the magnetic field or the electromagnet must be in motion, so where’s the paradox?

Re: eating meat

In the aggregate, it’s not. We industrialised societies as a whole do eat way too much meat, and it’s not, in aggregate, healthy. It’s just wrong to conclude from this that any one individual is eating more meat than they should – an average never tells you anything about individual data points.

The RISC/CISC distinction is largely obsolete nowadays. (F.ex. no one implements the x86 instruction directly in hardware anymore; all contemporary x86 CPUs translate x86 instructions into RISCish micro-ops while decoding, then execute those micro-ops.)
