The author began to realise the truth: that the quality of his writing is very low on average. Then he moved away from that realisation to the thought that Roam or some other kind of automation could somehow save him.

Perhaps what he needs is for the tool to automatically ask him "Is it okay to delete this note from 60 days ago?" That should be long enough for him to lose any attachment to what he wrote and a lot of the time he should say yes, and delete the crap.
