AI progress from 1960s to 2010 was exponential, but followed Moore's law and most of the progress was in symbolic AI and not connectionist. Part of the reason connectionist AI didn't make much advancements during this period is because they didn't get any increase in computational power dedicated to connectionist research in an argument formed by Moravec. From 2010-2020s, we've seen much faster progress in connectionist AI, and much faster than Moore's law, at least 6x faster. The doubling rate of progress has been 3-4 months from 1-2 years. This is still exponential progress, but at a faster rate than Moore's law.
