I solve this problem by occasionally yelling at bafflingly stupid current events, as recounted by various youtubers/podcasts.

Gotta keep up that ability to insult on the fly.

Stretch those creativity brain pathways, in addition to your vocal cords.

Either that or cursing myself out for writing bafflingly bad code, from time to time.

… Less insanely, I also sing, and… have neighbors I talk to, go outside from time to time, chat up randos.

I have an internal monologue nearly all the time.

Sometimes I just outwardly verbalize it.
