- Artificial Intelligence. Humans remain much as they have ever been as they nod off into irrelevance, coddled by the intelligence accreting around them, which carefully conforms itself to expectations. [Your phone is a far more powerful computer than those you grew up with... but show me the button you press that lets you write and execute a program on it.]
- Augmentation. Some few humans acquire weird new skills that let them use computation more effectively. The plasticity of the human mind is stretched to its limit. [Category theory is a prerequisite.]
- Group mind. To many minds, all present problems are shallow. It's just a question of getting the right information to the right people. [Hello reddit, violent young godling infested by parasites.]
It will be a mix, and in retrospect it will be obvious how far we already are down all three paths. It seems like the niceness of the singularity will be proportional to the extent the third option can be made to work, and I'd like to commend this option to anyone looking for an interesting project to tackle.
