Why the AI Capability Multiplier Has Compressed to 3.1 Months From 3.5

I have been tracking the progress of AI since January 2025, since Trump’s inauguration. Initially, starting at one, I pegged the doubling factor at 3.5 months; then I adjusted it lower to 3.3 on August 17th. After further research, I am settling it back to 3.1, which is 13.43 weeks. This is the time it takes for AI to double in raw ability, breadth, and the ability to create useful work.
Today, that number stands at 52. Think about it. AI is 52 times more capable today than 20 months ago.
