How long can NATO abstain from using killer robots?

That's the perfect example in favor of using "killer robots". I'm fully against Putin's invasion of Ukraine, but this is a legitimate military act. The risk of downing a civilian aircraft was zero. In a combat zone, the only flying objects are either friendly or enemy. Having a autonomous anti-air system that fires when an enemy aircraft is identified is not any different from having a landmine that explodes when a tank passes over it. If anything, land mines are more problematic, because they stick around after the end of hostilities.
Anyways as a counterpoint, imagine an asteroid hurtling towards Earth. Zap! Problem solved.
IMO it's going to happen anyway, better to get to grips with it early, develop better IFF for individuals and light vehicles, etc.
