> Apple is not going to change to RISCV after spending a huge amount to move their entire lineup of products to ARM You could say the same about Apple spending a huge amount of money to move from 6502 to 68000 (which lasted 10 years), or spending a huge amount of money to move to PowerPC (which lasted 11 years), or spending a huge amount of money to move to x86 (which lasted 15 years). RISC-V wasn't ready when Apple made their move to Arm64 in 2020 -- the base RISC-V ISA was only published in final form in July 2019 (RV64GC aka RVA20), many things needed for good desktop systems were added in November 2021 (RVA22), and Android for example is going to require the new RVA23 profile as its minimum configuration when the first devices come out around 2026. Apple could move to RISC-V from around 2026 if they really wanted to. In an extraordinary move they've signed up with Arm until 2040 -- 16 years from now -- but who knows what will happen in that time period. Will Arm even exist? Will Apple be the only company still using the ISA? At least with arm64 Apple is building their own cores and chips. Apple moved on from 68000, PowerPC, and x86 not because the companies ceased to exist but because they stopped making chips relevant to Apple, or the direction Apple wanted to move. But never say it's too expensive for Apple to move ISAs. They've done it four times already, they can do it again.
