Ok, so the title is a bit clickbaity. If you are appearing for an exam you of course need to remember what you read. But not everything that you read needs to be remembered.
Mo talking about how he reads and then forgets.
I read to forget. Even when studying or working on papers for a PhD, I approach texts with the same mindset: I’m not a storage device that needs to save all bits of information. I am more of a system of Bayesian beliefs, constantly evolving and updating in small, incremental steps.

From most texts, I only want two things: First, I want it to subtly alter my thinking, an incremental update that moves me towards a refined world model. Second, I want to pull out a few key pieces of information that I might use later in my writing.
This comment on Hacker News succinctly describes what Mo is talking about.
I cannot remember the books I’ve read any more than the meals I have eaten; even so, they have made me.
