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.
