You may have missed my footnote, where I addressed this?
To preempt a possible misunderstanding, I don’t mean “don’t try to think up new metaethical ideas”, but instead “don’t be so confident in your ideas that you’d be willing to deploy them in a highly consequential way, or build highly consequential systems that depend on them in a crucial way”. Similarly “don’t roll your own crypto” doesn’t mean never try to invent new cryptography, but rather don’t deploy it unless there has been extensive review, and consensus that it is likely to be secure.
