My Second Brain

Most people use artificial intelligence like a search engine on steroids. This book is for anyone who senses it can be much more.

Gabriel González Pineda has spent more than twenty years in technology, and the last few turning AI into the center of how he works and lives. Not through theory, but through trial, error, and obsession: more than a hundred models tested, memory layers built by hand, agents working in parallel, and more money than he'd like to admit spent along the way.

In the process he discovered something almost no one names: the problem was never the model, it was the memory.

My Second Brain is the honest account of that transformation, and a guide so you don't fall behind. You'll understand:

• The three-brains model: yours, your memory, and the language model.
• Why your way of working must adapt to the tool, not the other way around.
• How to give AI memory so it knows who you are.
• How to delegate to autonomous agents without losing control.
• And also what went wrong: the money lost, the hallucinations, the dead ends.

It is not a tutorial or a list of tools that expire in six months. It is a book about the principles that don't change, written by someone who learned them the hard way.

If you use AI every day and feel something is slipping past you, or if you feel lost among so much novelty and don't know where to start, this is the map you wish you'd had.
