I just skimmed it to be honest but a few things I would say; if the technology is there use it, or at least try it. That said does the technology actually do anything better than the real thing of being out on a pitch aiming for real team mates in a game situation? I doubt it. If the technology can feed to caches statics which can be interpreted in to useable application then great.

what a load of nonsense

I for one do not think it's nonsense. I wouldn't be surprised if some successful youth set-up employs something similar

I for one am shocked this has taken so long to be implemented. I mean it is basically improving a players technique, what more is there to say? And yes I agree that it would be much more beneficial to youth players (but you can say that about everything).

It's not going to do anything better than the real thing, no, but the point is that it is lots more efficient. You'd essentially need ten ball boys to replicate this exercise outside; it's just a lot easier to stick a player in a cage than to have ten team mates standing around while the one guy is practising.
