Meaning of "come at a cost" Hi. While I'm watching CNN 10 for learning English. I heard the phrase "come at a cost" and tried to look it up but no dictionary gives an explanation. Does it mean bad things happen as a result of what we have done? And is it the same as "come at a price"? This is the sentence the phrase is used. Robotic spacecraft would be doing the traveling and of course, all of them would come at a cost Thank you
