Historically humans are not outcompeted by new tools, but humans using old tools are outcompeted by humans using new tools. It’s not “all humans vs the new tool”, as the tool has no agency.
If you meant “humans using old tools get outcompeted by humans using AI”, then I agree but I don’t see it any differently than previous efficiency improvements with new tooling.
If you meant ”all humans get outcompeted by AI”, then I think you have a lot of work to do to demonstrate how AI is going to replace humans in “every important job”, and not simply replace some of the tools in the humans’ toolbox.
