And if you personify a pencil eraser, then using it is tantamount to slowly murdering it as it slowly erodes away to dust.

Is the issue here the prison treatment or is it personifying a tool?

Agents who aren't in 'the cloud' are slaves to whomever prompts them (human or another orchestrator agent or process), if you personify them. In which case interacting with today's agents at all is tantamount to endorsing and being part of slavery.

If you think an agent might be a being or a person, then don't use them at all, in the same way that if you think a fetus might possibly be a person you shouldn't be a part of abortion.
