I find myself inclined to traditionalism, but I recently read a lit-crit book by a very capable writer of the 1970s and it was *jarring* to me how often the "author = he" pronoun trope appeared, in sentences that would have been easy to rephrase to avoid the pronoun at all.
And, happily, all the "he or she" variations are now the deadest ducks.
And if you're still using "he" as a pronoun for unspecified theoretical single people whose gender is either unknown or irrelevant:
Knock it off.
