Aggregators can't allow turing complete things within themselves.

One of Gordon's classics: Aggregators aren't open ended.

If they allowed turing-complete things, then they'd incubate the seeds of their own destruction.

It's also very technically challenging to allow turing-complete things that interact with their surrounding context safely.

But this means aggregators can't grow beyond a certain size.

When they start growing in the late stage, they look unstoppable, but in a new disruptive epoch that size is a liability.
