Stream entry (pali sotapanna) is a meditative attainment that signifies an important point in a meditators path, Kenneth Folk allegorizes it as the point where you cross the top of a hill with a bicycle.

Since streamentry is difficult to attain for many people, one may be interested in when, if at all, neurotechnology can aid in its attainment, and if so, how soon.

So this question: When will we get a product on the open market that allows for ≥90% of people to reach streamentry via ≤14 days of consecutive effort and ≤$10k of expenses?

I unfortunately do not have any notable meditative attainments, or a reliable way to judge if someone has them, so I'll have to rely on gut-feel, meditation teachers evaluating it, and AI systems of the day to make a judgement.

This question resolving positively would represent a substantive paradigm shift in technology aiding contemplative progress, and thus may require transformative AI to be developed first. (First realized this after reading this shortform by Eli Tyre).
