Substitute AI with computer intelligence. Of course as computers become more and more advanced, computers will replace more and more human activity. That of course goes for trading as well.
ChatGBT is just a reference for how advanced a computer has become.
So what I allow myself to tell the newcomer that wants to give up his job is that he should be aware when he chooses this career path that he will compete with computer intelligence at a level that did not exist when I started 14 years ago and that it will accelerate in the coming years.
i started 20 years ago, and there are just as many opportunities to earn as there was back then. those opportunities are different but at the end of the day, people are risk averse and will compensate you to take risk.
