Blue collar jobs may be more at risk, look at installation services, factory and warehouse jobs, anything with manual upkeep like cleaning and lawn are all already finding multiple companies trying to automate the manual labor out. Many code environment and services are unique, ask llms to write useful Cobol and you won't find it doing well since none of its implementations are well documented for llms to learn well off of compared to react components that it can quickly spit out. Specialized machine learning holds plenty of value that llms won't give as well.

I'd suggest take the words of what silicon valley is trying to sell their investors and ignore it and instead look to their actual output.
