I don't think such large questions are served properly with "good" and "bad," context is important. If, for example, the woman in question had no previous knowledge of what a proper relationship looked like, and realized that she was depressed because her husband worked all day, drank beer all night, berated her every effort at making him happy, and couldn't fuck worth a damn, and left him and found a new husband that made her happy? Then I'd say that's terrific. If on the other hand the woman in question was a satisfied, happy homemaker, with a husband who did all he could to make her happy, but then was given an artificial AI sex-bot boyfriend because her husband needed to travel overseas for several months, and she became so enamored with this machine that it undermined an otherwise healthy and productive relationship because no human being can ever truly match up with a simulated one who's sole reason for existence is making another person happy, and as a result, their marriage fractured apart and their children grew up in a split set of two poor households as a result? I call that pretty shitty.

I'm not saying ban sex-bots. I'm saying we should be asking why this is a thing people want and maybe try addressing the actual social ills here.
