I'm guessing if LLM's right now can do such multiple tasks and they pretty much can easily pass the Turing test,I'm guessing by GPT5 then. GPT4 will be announced soon enough,either late 2023 or 2024 and it will be game changing,and by that time BIng AI and Bard will be great additions in the industry,so by 2026-7 we will have GPT5 so I guess that's when the curve will start to happen. These language models will prove so good at multitasking. Man the 2020s are going to be WILD! We are facing the biggest technological innovations that humanity will ever get to see right now in front of our eyes.
