No one needs to build 'em. We are our own downfall/worst enemy.until, of course the robots build mindless miner/worker drones.
We breed/produce them, "by accident"; "not my fault"; "society be owin' me, 'cause...," then absolve ourselves of all responsibility by turning 'em over to "the machine" for 10-12+ years and marvel/wonder at why the subjugated/unionized/can't hold other meaningful employment/lowest bidder didn't deliver what we wanted, as we wanted it, and when we wanted it.
Then we hope/pray that it is not actually what it was never, EVER, gonna be, and let go let____. QUIT.
This faction of "society" deserves all it gets, x10. The rest of us don't. JMO.
