First time poster here, sup?
Now, addressing the comic: there are many incredibly valid points to not hiring AI employees, the first and foremost of which is the most obvious - they aren't human. When there are fully qualified people applying for the same position, the decision to instead "hire" an AI is, frankly, immoral. The employer is making a conscious decision to contribute to poverty and human suffering, even if his intentions lie elsewhere (the road to Hell and all that); most likely with his profit margins. It is comparable to self-service machines taking the place of people, or assembly lines being staffed with robots.
Frankly, I agree with the boss in today's strip. On top of being literally inhuman, May exhibits other qualities which would be red flags for any intelligent employer - she has a short fuse, she curses, she is confrontational, she has a sarcastic streak a mile wide, etc. Moreover, the idea of any kind of Robot Civil Rights is outright ludicrous. Machines are our tools, not our equals. We make them in order to accomplish things we cannot on our own, and if we gave them the ability to both think for themselves and Freedom of Action, we would be stepping into our graves. These are not genetically engineered humans, which is a whole 'nother kettle o' fish, these are constructs of metals and composites loaded with data made to enhance our lives, nothing more.
Empathy is reserved for living beings. Machines are not alive. A mimicry of a human mind contained in a robot is not alive, it is merely a simulacrum of life - a testament to its engineers' ability, to be sure, but that is all.
