$7.5 million is a drop in the very large bucket that could make such a scenario possible, yet the very existence of the bucket should wake us up and think about, and sort out in our heads, what is "right" and "moral" and "ethical."
There have been many and complex arguments taking positions at extremes such as "of course computers will be sentient (and soon!)" to "machines can never achieve awareness that humans do," and every slice in between.
If you have already thought about what you mean by these words, excellent. If not, now's a good time to wrap one's head around this nontrivial topic. Can an autonomous robot make moral decisions? Public policy on it depends on thoughtful input.
