MIPS goes open source

Without question, 2018 was the year RISC-V genuinely began to build momentum among chip architects hungry for open-source instruction sets. That was then.By 2019, RISC-V won't be the only game in town.Wave Computing announced Monday that it is putting MIPS on open source, with MIPS Instruction Set Architecture (ISA) and MIPS' latest core R6 available in the first quarter of 2019.

Good news, and it makes me wonder - will we ever see a time where x86 and x86-64 are open source? I am definitely not well-versed enough in these matters to judge just how important the closed-source nature of the x86 ISA really is to Intel and AMD, but it seems like something that will never happen.
