Building a robot army is a ridiculous idea.

The efficient & practical way is to stop renewing residence and work visas, making acquisition of visas harder through complex demands of high language proficiency, and a high amount of money as proof-of-funds, perhaps requiring a local referral too. It's what countries that don't want immigrants but don't want to say it out loud do.

They add job requirements (aka skilled migration) and lottery system on top too !
