The article doesn’t imply genetics have no effect, it just treats them as a baseline which are then adjusted over time according to the person’s lived experiences.
Likewise with mental disorders and depression, the “solution” you claim it states as “not being mentally ill” is the outcome of a process, not the process itself.
My point is not that doing these things is never beneficial (well, one may argue about the psychedelics lol), just that it oversimplifies the problem space (and solution space) to the point of not being useful advice.
In our experience, psychedelics are very hit-or-miss depending on the person. Some (like us) take high doses regularly without much consequence, others can suffer terrible damage after just a single dose. It can be difficult or impossible to predict, anyone who's unwilling to take the risk probably shouldn't.
So like the randomization process that seeds the values for RNN weights?
And the training rules, that determine which weights are adjusted in response to what units.
