1. The author proposes to replace college by "a modern curriculum that, on average, will produce people better prepared for real life than college".
2. This curriculum "can be funded initially with $5000 for poker".
3. This is because after the first dedicated year of learning poker, "you'll be able to make between $45-60 per hour for the rest of your life".
4. If you follow this plan, your "chance of being self-sufficient and prepared for 'real life' is about 90%".
Let's boil this down even further: the author posits approximately 90% success rate -- for everyone -- for a scheme funded by generating an income of $45-60 per hour from a zero-sum game.
"Completely f'ing delusional" seems accurate to me.
