I am currently advocating for the free use of mind expanding tools such as psychedelic drugs. Here in Holland the laws arent quite as bad as most other countries, but they contradict. For example: it is okay to buy/sell and use weed, but not to cultivate it. Mushrooms, Ayahuasca, Mescalin cacti and Iboga are legal, but MDMA and LSD arent, and thats a shame. Also, there is still some stigma on using it, which prevents people to have mindblowing, life changing experiences.
I am also currently researching quite a bit about Bitcoin and the Blockchain in general, which in my opinion is going to change everything in the next few years. Not so much about the money, but Blockchain will democratize ownership, referenda, voting, contracts and cloudcomputing in a safe watertight way.
