LLMs have two avenues. One is the realm of self improvement in fields with verifiable output like programming and math. The other is natural language where they can't generalize super well, and therefore need a lot of new training data. Today new data means interactions with an LLM, which is what only the leading chat providers have. In both cases they will continue to improve and slowly replace white collar jobs. The biggest bottleneck currently is lack of hearing and seeing capabilities which isolates LLM training data input to entered text mostly. Once they start interacting with people by observing their behavior, almost all knowledge will be trained on. Then they will become adept lawyers and psychologists. Behavioural understanding can be only 5 years away. After that they will be limited by their navigation , i.e., robotics.
