I went to university with a Comp Sci major who looked an awful lot like a very young Prince Phillip, (he wasn’t, this was a US university, and he’s about 4 decades too young) who could barely function at all sober. Give him some weed, and he’ll debug your mess of a program and explain what you did wrong in less than 30 minutes. I watched as he coded, and documented his own OS on LSD over a period of about 12 hours once.
