Glossary
AI - A computer programme that has been designed to think.
Neural - Relating to the nerves.
Singularity - The point at which something becomes infinite.
Exponentially - Exponential growth is when the rate of growth increases steadily over time, for instance by doubling: 1, 2, 4, 8 rather than 1, 2, 3, 4. This kind of growth has the capacity to lead to dramatic changes over relatively short time spans.
