because if you say, oh, here's siri or qutana deciding what you should read or whatever algorithm it is, cibc we're social creatures we tend to defer to them. but what it does is it creates this obscurity. because if we're honest, what it is is it's some stupid algorithm that -- none of these algorithms are that great yet. i'm very proud of what our field has done. but at the same time we have to have some perspective. and recognize that it's still pretty crude. and what we should really be doing is visualizing for people what the algorithms are doing. giving them access to understanding the mechanism as much as possible so they have an opportunity to understand their world better as doug would have expected them to. we should expect more from 0 you are people rather than we've automatically chosen these things and chosen like the latest one from facebook is what things from your past you should remember. well, that's ok. but i don't mind -- i don't mind facebook offering that service. but i want them to make visible that algorithm so people can look at the mechanism and see what the corpus i

everybody is asking this question, how low will they go joining us from the oil and gas conference cibcategist katherine you must have if answer to this katherine how low will oil prices go from here? >> well, i do my best but a tough market. >> okay. give us your best shot. >> really? >> well, i think that we have a little bit longer down here lows but i do think it is positive are to separate out short term from what we see happening in the he longer term or oil i think there is a temptation when we get to extremes to think that is where we will be forever, that is never the case. >> i don't mean to beat up on you we bring you on this is what you look at sib merging in this you are hedging your response there has to be price levels that you are watching, that are key, say if we fall below 40, 39 dollars a barrel, that we could see another so dollar sell-off in there give us something to look at here. >> i think we could have few more dollars downside i think we are fairly close to the bottom, and do i think we will certainly end higher, in brent, we are looking for about a 10 dollar r
