You could use GPT-3 in 2020 but it was expensive and difficult to make it behave. Iterations of GPT-3 starting in 2021-2022 allowed it to obey commands (InstructGPT) and made it more feasible to "engineer" with it.
The true inflection point was due to free, accessible and good-enough-quality AI generation in the form of Midjourney and ChatGPT.
