It isn't really general intelligence if it doesn't compete, or outcompete us, at a large enough portion of knowledge work jobs that we are forced out of the labor market.
Also don't forget that plenty of knowledge work is focused on automating manual labor. If AGI is a thing, it will eventually be used to also outcompete us on physical work too.
People like to point to plumbers as an example of a safe(r) job, and it is. But automating plumbing tasks is most difficult because the entire industry is designed to be installed by humans. Without that constraint it would likely be much easier to design plumbing systems and robots to install and maintain them more efficiently than what we have today with human-optimized plumbing.
