Honestly, I’m doubtful those are the answers. Most of the cybernetic enhancements to your brain would be be inferior to making your organic brain work better. The ones that are superior would be upgrades instead of respecs. Genetic engineering wouldn’t be a respec as much as a redo of a bad dice roll for base stats. Many of the mistakes you make in your early life through choices can be solved by medicine healing injuries, extending life for more time to relearn, or by creating societal systems that allow people to right their wrongs.
