if only it wasn't that expensive to get a license for x86

x86 isn't that good. RISC-V has similar code density as amd64 while being fairly simpler. There's not much appeal to x86 as an ISA, other than for running legacy software.

running 'legacy software' is for most use cases probably the most important feature.

Most "legacy software" can be rebuilt from source code. For software where the sources aren't available, there's only a small subset where performance is the main priority. The rest can be handled through emulation.

The last time I checked, the patents have expired on anything pre-Pentium, and by now the Pentium patents probably have expired too.

I am aiming for the expiration of Intel patents for stuff up to SSE2, which will likely happen in the next few years.
