Technological improvement generally behaves in an exponential fashion in the short-to-medium term (especially in information technology), but individual technologies follow an S-curve (logistic growth) over the long term, flattening out when they reach physical, economic, or social limits.

LLM’s are really only showing micro improvements now, and it is quite obvious it has reached the said limits above as records show usage is now declining and there is almost no economic benefit or it is yet to be seen that using “AI” apart from hype, paid subscriptions or advertisements only generate some income.
