Thanks for your explanation. I see you have had quite a time here and much more experience than me; so your words are of knowledge and wisdom :)
Still for me, I dont feel good with intensive use of them (as I see some people do)

But look at future life, maybe we have to accept them even in life! Maybe I don't see the bright side just for the feeling and lack of experience. Cause in the end these bots may let you contribute with more real people too and penetrate better...
