I disagree with that characterization of AI as not accelerating over time.
AI as we currently know it as been part of public perception for less than 10 years. In 2014, asking a computer to figure out if a bird was in a photo was essentially impossible (
contemporary xkcd comic). However there was already a breakthrough brewing in academic circles. It wasn't actually a new algorithm, but the understanding that certain sorts of algorithms produced better and better performance when trained on really big piles of data. <-- seems obvious in retrospect, huh?
2015, computers started to exceed the performance of human beings at certain, narrowly defined, tasks related to recognizing handwritten letters.
2017, AlphaGo (trained on huge numbers historical Go games) beat the worlds top ranked Go player. And in 2018, AlphaGoZero, trained on nothing more than the rules of Go, beat AlphaGo consistently.
2018, Computers out perform dermatologists at accurately identifying skin cancer.
2020, AI can accurately predict protein folding with trackable amounts of computer power required, a big rate limiting step in biology (we'd been dependent on someone being able to crystalize the protein so it could be imaged which is labor intensive, slow, only works for certain proteins).
2021, text-to-image generative AI first becomes available.
2022, Within a year the photos produced by AI from text prompts are so realistic they are winning
photography contests (not just art contests, but it is winning those too).
Also 2022, the first large language models become publicly accessible (ChatGPT, built on GPT3.5).
2023, ChatGPT's output in good enough lawyers use it to replace writing their own legal briefs (not a good idea) and asking ChatGPT to explain how to do things or what a given error message means has largely replaced asking professors or TAs for help when learning to program (personal experience).
Also 2023, Thousands of people are willing to pay $1/minute just to have phone calls with an AI clone of some person they follow on social media.
Also 2023, Amazon is flooded with self published books full of AI generated content and AI generated photos.
Also 2023, Television and movie writers have been striking for the past four months in part because they're genuinely worried about having their work replaced in whole or in part by ChatGPT and its siblings.
Overall we're not very good at predicting what AI will do 2-3 years from now, but based on the history of the last decade it'll continue to outperform humans in more and more arenas at an accelerating rate.
