The default argument that such a development would lead to a foom is that an insight-based regular doubling of speed mathematically reaches a singularity in finite time when the speed increases pay insight dividends. You can’t reach that singularity with a fleshbag in the loop (though it may be unlikely to matter if with him in the loop, you merely double every day).
For certain shapes of how speed increases depend on insight and oversight, there may be a perverse incentive to cut yourself out of your loop before the other guy cuts himself out.
