At any given time, I have about 20-30 books tagged as "currently reading" on Goodreads[0]. So, something I've started, read at least a bit of and then stuck a bookmark in.

Realistically, at any given time there are 3 or 4 books that I'm dedicating meaningful cycles to and expect to finish "soon'ish".

Right now the ones I'm seriously working on are:

Superintelligence - I've heard so much about this book and keep hearing people talk about the dangers of AI, and while I already have an opinion on the subject, I thought it would be interesting to read what Bostrom had to say.

Abductive Inference Models for Diagnostic Problem-Solving - an older book on an approach to automated Abductive Inference called "Parsimonious Covering Theory". I'm not just "reading" the book, as in reading it straight through like a novel, I'm actually working on re-implementing PCT using a more modern software stack, with a goal of doing some research into possible ways to use abductive inference in conjunction with other techniques (neural networks, reinforcement learning, graph-based knowledge-representation, etc.)

Artificial Intelligence: A Modern Approach - such a class in the field, I felt like it was time to finally sit down and the read the whole book, cover to cover.

I just finished Sphere, and came away a bit disappointed. Before that I read I Am Legend, which was excellent! It has nothing to do with the movie at all.

Even though it's been out for a while, I finally read "The E-Myth Revisited." The concepts are simple and it gets a little long in the final quarter of the book, but in general it is a fantastic book that every entrepreneur should read at least once.
