We had three waves, the agricultural revolution, the industrial revolution, the information age, and now AI based on neural networks creates new kind of content, text, images, audio, video. They write already Wikipedia articles, they outperform humans in finding mathematical algorithms, is this another breaking line, is this the fourth wave? I see currently AI split in a lot of dedicated weak AIs with specific purpose, do we have a strong AI incoming, an AGI, artificial general intelligence, which will combine all those into one big system? Interesting times.
