Electricity is usually much much cheaper than food calories — 2500 kcal is about 3 kWh, apply your local energy and food costs — so electricity won’t be the limiting factor, but construction cost/longevity and AI quality will be.

Assuming equal capacity (not any time soon but might happen eventually), anywhere that electricity was cheaper than Germany’s famously expensive average of US$0.45/kWh would be able to afford to replace any human labourer with a robot, even if the humans were at the UN threshold for abject poverty (US$1.90/day, which is why I gave German electricity in USD rather than EUR) and that human somehow worked productively for 33h45m per day.
