Stoicism hasn't been popular since Victorian times. I think SV types and rationalists kind of revived it, since it was moral austerity without any real religious background. To an extent they do the same with meditation; it's somehow gone from being something associated with New Age thinking, to something atheist rationalists tout the benefits of while carefully avoiding any hint of spirituality.

Everyone I know who identifies as a stoic is an emotionally stunted software engineer who realistically isn't tasked with stoically shouldering very much of anything.
