Re: By 2025, ‘sexbots will be commonplace’ – which is just fine, as we’ll all be...
No way I would prefer sexbots over real girls. If you haven't tried real girls try it, you will not look back to your sexbots. 
Have you tried a sexbot ? How can you be so sure about it. Probably in 100 years most of us won't be able to distinguished between the two of them.
I'm in no way promoting this kind of activity which might lead to more people turning into "Hikikomori" or "shut ins" (japan has already a huge problems with this but don't be so sure about how those will perform their duties.
No matter how they do it, real women is always the original and sexbots is always the copycat trying to copy the real women.
I think the real advantage of sexbots is it will not dump you.
Even right now robots are doing a lot of things better than human. I'm not going to say they will do this also but time will tell.
Don't forget that with a robot partner you could program her to like some things you're girlfriend doesn't like
Yes. Free will is a over exaggerated if you think about it.
You can program the bot to "like" what ever you did and whoever you are.
