This is less relevant for logos & creative works, but things that enable companies to do production will go back to being closely guarded and sharded secrets, which is what the patent system was trying to resolve (though we can certainly argue the success of it).

If companies fail to protect their investments in generating IP, they will stop investing in generating it.

And unless IP generation costs (all in, including the humans telling them what to generate) fall close to zero, it will be bad for the world if companies cannot recoup investments in generating new IP.

We would expect this to hit those industries relying on IP protections the most, e.g. pharma.
