A fellow named Joshua Scott Hotchkin, who has a blog named
Advanced Dank Unicorn, recently posted a piece called
"Why You Should Be Skeptical of Timothy Leary’s SMI2LE Formula." This is a followup, of sorts, to Hotchkin's other recent piece,
"The Eight Circuit Model of Consciousness Is An Egotistical Abstraction," which he claims is "fraught with issues, even as an analogy."
Hotchkin has been using Facebook to propagate his theories, and as you might imagine, it hasn't gone down well with many Leary/Wilson fans. Richard Rasa ventured some criticisms, and found himself blocked by Hotchkin.
It seems to me that the Eight Circuit model remains alive, at least in the sense that people still find it useful, as I've documented on this blog
here and
here. As for SMI2LE, there are plenty of Silicon Valley libertarian types who are trying to make space migration, intelligent increase, life extension and all of the rest of it a reality, and spending real money to do so. A blog post by a fellow in Iowa doesn't change that.
Rather than address Hotchkin's points, arguably not worth my time, I want to make a general point about models: As RAW would say, you use them insofar as they are useful.
To put it in Buddhist terminology (from one of the Pali sutras), a raft is for getting across a river, not constructed to serve as a burden to carry around indefinitely.
As I write this, the disease model for dealing with opioid addiction has become popular in the U.S., because it solves certain problems. It removes the stigma from getting treatment, it allows people to focus on solving the problem rather than discussing the alleged failings of the person with an addiction, etc. No doubt there are points where the disease model might fail, or at least could be debated, but it remains alive because it is useful.
