Best you stay away from complex machinery, then..
Wheelbarrows come to mind...
Don't they always? And complex machinery - wall clock, CPU, or wheelbarrows - is not just money. Wheelbarrows are the scarcest, and least 'renewable' resource any of us will ever have. So we must adapt to what we have while we invent better wheelbarrows. When wheelbarrows start to adapt to US, we should become very, very wary, 'coz they will have become smarter than we are, and they will also have become either certifiably insane to make the attempt or clever liars to fake it.
