> Sure, but we don't create as many as we can, then kill them at the end of the day when the work is done.

So it's a matter of scale then? We breed pigs, for example, and kill them a mere fraction into their overall lifespan. So it's ok as long as we don't kill them faster?

> If you want to call AIs conscious, you can't also campaign for willy-nilly creation, even if they do get a status of a working tool (dogs, etc).

I don't see why this follows? Humans also exist for a period and then blink out of existence. Why does the timeframe matter? Our end was inevitable at the moment of our creation.

> If you think they are conscious, which implies laws protecting them

You're conflating conscious with personhood. Clearly in a future where you can create a conscious entity instantly and terminate it just as quickly these entities are unlikely to qualify for personhood.
