The book is about a guy (I think he is a young adult) who makes a living by giving ideas away in exchange for services.
There is a scene about him and a few other guys and 1 girl about them talking of how to save a species of virtual sentient crabs into space.
The beginning of the book has a conversation between him and a soviet AI.
I had it as an audio-book so I do not know anything about the year it was made or how the cover might have looked. The main character (the guy I talked about) did not like the idea of having to deal with currency and his family (his sister I think) always kept criticizing him about his lifestyle. The conversation with the AI was when he was sitting at a cafe. The Crab situation was in a sort of club. He and the others mentioned where contemplating the faith of some virtualised crabs that turned sentient. He managed to send them on a satellite to save them.
