In a larger sense, this is true, for now. But it's not a reasonable shortcut to supply information that is presented as correct but is in fact partially made up. Either there will be a well deserved public backlash, or in a pretty real way, reality will be irrecoverably warped.

It's pretty hard to imagine any answer that is useful, no matter how trivial, if it's wrong 20% of the time. Deep Learning is an amazing parlour trick that can be useful in the right circumstances, which basically means an expert has to be present to interpret its results.

I'm not convinced having a fully padded conversation is what people want. I find it annoying. Google was on the right path with snippets, they just need to make them easier to consume and emphasize the fact the search can be continued. I think Google is being very conservative, partially for safety reasons, but also because they won't take chances if they don't have to.

Of course, all these searches would be much more useful if they had more intimate knowledge of the searcher, but that's another dangerous path.
