I printed a ton of books from libgen in the past 10 years.

Using paper just works better for me.

I do use LLMs for asking questions, and other learning tools.

I almost feel nostalgic for the bittorrent era, when piracy (or unauthorized distribution) was done the old-fashioned way!

Though it's a shame that current copyright law is incompatible with building an effective digital library that isn't crippled with restrictions designed to impose the limitations of paper books (or worse) onto ebooks (while removing benefits such as first-sale doctrine.)
