Biologists take ethics much more seriously than any computer engineer or computer scientist that I've seen.

I saw a very notable scientist talk about topics like this and how they wrestle with them. Things like a "gene drive" [0] are being experimented with in the world [1], and biologists think very hard before doing certain things with the powers they wield. And I have not heard a life scientist laugh off ethical or spreading concerns when a thoughtful question was asked... but maybe the interview you're thinking of was a more lighthearted one?

My point isn't so much about the work ethics of one or another but rather than systems, even interconnected ones, are rarely as genuinely interdependent as science fiction drama lead us to believe.

Yes there can be terrible catastrophes e.g Fukushima, but what actually happened, within which extremely rare conditions, versus what we freely imagined is quite different.

We might need more reminders of those risks to properly insure such systems don't lead to the collapse of one to another (sadly) but still we manage to learn from it.
