I wholeheartedly agree good sir!
Although "babysitter kiddies in space" can go right to hell...
Wild ass theory as to Clara, with no substantiation other than my own conspiracy theory gland acting up.... The Tardis created her spread across time, as mentioned earlier part of the Tardis "DNA" is that is builds any tool you need. THe Time Vortex has had a human form before (The Doctor's Wife) so could have learned how to "build" a human that he would need and drop that human off at times he would need it. The Clara we see now ends up being the template for the Tardis to use to create the others. It programs them similar to the way the chameleon circuit reprograms the doctors memories when needed. Of course probably completely off my rocker, but there it is.
As for who will pick up the mantle when Smith hangs it up???
