The thread argues that AI investment is growing much faster than real enterprise adoption.
- AI investment has been expanding at about 40% a year, compared with 25% for electricity and 16% for IT in comparable early periods.
- Yet only 19.8% of U.S. businesses use AI in at least one function, and just 11% of the S&P 500 has deeply integrated AI.
- The author says the bottleneck is not capability but trust and implementation, and claims enterprise spending on continuous evaluations is still far below what it should be.
- The proposed fix is to build evaluation loops that define what “good” means for each use case and measure systems against that standard continuously.
