I have started reading more books and I am realizing how I have to retrain my eyes and my brain to read full sentences for real comprehension. because I have become so used to skimming and reading summaries of summaries from LLMs. I don't know if this skill is fundamental but I do think that my mind feels a bit mushy.
But despite being mushy my brain works fine with math and other formal systems. Like the actual reasoning is fine but the first interface from Natural Language -> Argument Structure is more noisey.
