> Ok, tell me what good it is going to do to consider those things.
Well, assuming you're American, you can look at the decline of Detroit to see what happens when you don't think of these things. Or Wales and the North of England, if you're from the UK.
> Are you suggesting that if we all collectively decide that building such things hurts people, no one will build them?
No, I'm suggesting that we consider the implications of what we're creating and try to ensure that, even as we build them, we ensure that we don't damage whole swathes of society in doing so. But that's just me, and it might just be that I'm a bleeding heart. All progress comes with its benefits and its downsides, and if you think rendering people unemployed without giving them an alternative means of supporting themselves is OK and/or shouldn't be part of the calculus of how progress is made, then that's your decision.
