I have made most of my money as a freelancer making weird integrations between legacy systems, migrating data that no one knew anything about, building or designing systems people weren't even able to formulate in any coherent way to me as a human and without having to change all the things they were certain they needed, when they found out that they really did not. Building the thing right vs. building the right thing. I am not saying that AI will not be able to revolutionize a lot of areas, but solving well known coding competitions are far removed from where a large portion of coders and technical people make their money.
