Chatgpt is good but as soon as there's something better people will shift over very quickly.
One thing it lacks is reliability. You can't trust its answers all the time. I suspect the next goal is to create reliable expert systems that people can trust. I see a future where companies will buy access to a reliable expert ai that will help their workers do their job.
Eventually there will be so many expert systems that they can be tied together to create what seems like super ai. It won't be a thinking machine but it won't matter. It will be so realistic that people will believe it's a sentient machine. I bet it will happen in less than 30 yrs.
Imagine a company like AWS renting their AI system to do a specific function. It's going to be interesting.
