That couldn’t have helped. Otherwise I feel like RISC-V is better if you want to build something new from scratch.

IBM spun out their foundries to Global Foundaries (formerly part of AMD) a decade ago, then refused to commit to Global Foundaries next major process upgrades.

Staying on the bleeding edge of silicon requires massive investment, which they weren't willing to make.
