I’m just a fucking idiot
I doubt that he's an idiot, if you're using technical ability as the metric here (i.e. talking about Meta's engineers). He's certainly written code himself.

The New Yorker noted that by the time Zuckerberg began classes at Harvard in 2002, he had already achieved a "reputation as a programming prodigy".[7] He studied psychology and computer science,[14] resided in Kirkland House,[15] and belonged to Alpha Epsilon Pi.[7] In his second year, he wrote a program that he called CourseMatch, which allowed users to make class selection decisions based on the choices of other students and help them form study groups.[16] Later, he created a different program he initially called Facemash that let students select the best-looking person from a choice of photos.
It does kind of suggest that you could do much more elaborate printing in that fashion using smoke-equipped drones.
