You're describing a standard S-curve (logistic growth), which is definitely what happens to parameter counts or user adoption (like The Internet). But Amodei is applying this to scientific discovery itself. He’s effectively saying the "S-curve of Science" flatlines because we figure out everything that matters (curing aging, mental health, etc.). My whole point was that science doesn't have a top to the S-curve - it’s an infinite ladder (as per Deutsch).
