I don't know. IntelliCode has been helpful a couple of times. For example, I once had to edit a whole bunch of lines in a way that was very similar, but not so similar that it could be handled by a find/replace. After I did that for three or four lines, IntelliCode popped up with a suggestion that changed all of them in exactly the right way. That was nice.
However, in the vast majority of cases, IntelliCode suggestions are obviously-broken crap. Most of the time, its suggestions wouldn't even parse, which looks weird to me; surely they could at least filter out suggestions that don't pass the parser?
Now, I did read the article and I know that we are not talking about IntelliCode here, but I suspect the same basic problems apply. How many times you get a "wow" moment, compared to a crap moment? If the ratio is bad enough, you'll be better off not using it.
