The systemd developers have been active in the DE mailing lists, encouraging them to make systemd a dependency
I am shocked -- shocked, I tell you -- that one of the lead developers of a piece of software would encourage others to use it.
We could take a break when we hit a creative block.
Take that crap with you to Canada, you Commie.
So it's essentially inconceivable that any drug could make you creative. However it seems plausible that some drugs could act as a kind of adjuvant to creative struggle when you're approaching a creative breakthrough. Such breakthroughs often come at a time when you're critical faculties are slightly deranged; when you're exhausted; dropping off to sleep; or just say "screw it for now" and do something unrelated.
Hell, I've solved weird computer problems before with a case of beer sitting next to me. I'm one of those weird people where micro-doses of ethanol -- say, downing can after can of Pabst Blue Ribbon -- actually mostly has a stimulant effect. It excites the part of my brain that likes alcohol but it doesn't get me drunk enough, fast enough to have the "downer" effect that it's supposed to have. (Real ale, wine, liquor, different story.) It will actually allow me to stay up all night, and at around 3am -- et voila!
You are conflating psychedelic use with opiate use.
A friend of mine used to do Olympic style weightlifting (the competitive kind, not the bodybuilding). His coach used to tell him that back in the 60s and 70s, those guys would down anything they could get their hands on. None of it was very well researched, so there were lots of theories about which ones could potentially be "performance enhancing." LSD was definitely something they were using, and it wasn't uncommon to see lifters have complete freakouts on the platform (though to be fair, they were probably on a ton of speed at the same time).
I had a high school friend who was a fan of LSD. Saying it isn't addictive is a lie. He was constantly touting the benefits, which I didn't see in his life.
Having a negative impact on your life is not the same as being addictive. Eating candy bars can have a detrimental impact if you do it enough, but that doesn't make them addictive substances. Sounds like your friend was just a big fan.
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
