All of Musk's miraculous innovations come from 1970s Popular Mechanics and Popular Science magazines. After that point, there was a serious squash put on innovation. From multiple directions. Like the sciences, new theories were squashed or ridiculed out of existence. All the big papers didn't allow anything that wasn't approved.

Psychedelics really do not help too much with innovation, at least not deep stuff. Because, take cannabis for instance, it frees your mind to explore, but it also clouds your mind to any of the real specifics you need to look for.

Ayahuasca is interesting. Do not use it recreationally. YOU WILL DIE. Whether you live or not after the experience, you will die. And you need to be of sound mind enough to accept that.

Only use Ayahuasca in South America with Shaman who know what they are doing.
Ayahuasca is tied to that area. Tied to that land. Tied to that people.

Meditation is what you need to practice to gain mental clarity.

A parable i was told: "LSD is like a train ride through Buddha land. Through training your mind, meditation and spiritual practice, you learn to go to Buddha land all by yourself, and can explore to your hearts content"
