But… does it do commentary like “one is binding”, and does it try twice to see if it was a fluke? :)

I was surprised that those thin copper wires can actually push the pins up, I thought they would slide off to the side or compress themselves against the more solid/rigid pins.

I wonder what makes it take a minimum of 0.7s per combo, it seems like it could be sped up substantially.

On the mechanical side there would certainly be some challenges (having to work within a key that's all the deepest cuts, using something that could push up to "shallowest cut" level without deforming, general structural strength problems) but once you had a viable insertable key portion built you might be able to read a lock based just on the amount of spring resistance at each pin. You could also provide tension while probing for pins under tension. If covert agencies don't already have pretty portable devices like that it's because they don't care enough to create them not because of some true technical problem with doing so.

The devil is in the details though, there are some subtle features that need to be incorporated into the mechanics for the sputnik to work right. I have built a sputnik from scratch before, only after talking to Oli Diederichsen at a LockCon did I get some additional clues.
Also, I think there are plenty of other interesting things one could do besides brute forcing the lock with a simpler tool. Falle Safe has a single-wire variant on this for decoding locks. Again, the devil is in the details, just ramming wire up a pin stack doesn't get the job done.

I've seen too many Lock-Picking Lawyer videos.

rather inelegant, similar to an autodialer for safes.
i was hoping to see something that worked like a human lockpicker!

Somewhat less impressive than I was expecting. The wire idea is neat though.

Access to computers - and anything which might teach you something about the way the world really works - should be unlimited and total. Always yield to the Hands-On Imperative!
All information should be free.
Mistrust authority - promote decentralization.
Hackers should be judged by their acting, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.
Don't litter other people's data.
Make public data available, protect private data.

Further, while standing somewhere for five minutes may be obvious in some situations, there are many cases in which it wouldn't be obvious at all, or the response time would be great enough that this could still be quite useful to bad guys.
Finally, "security through counting on slow hardware" is probably even worse than security through obscurity.
