And despite a few pieces of evidence that kind of suggest that, it's still a lame plot twist. Orochimaru was using computers, CCTV and highly advanced medical equipment while Konoha was posting old-fashioned sentries. Part 1 has radio even though this almost never gets used again. Technology has always been advanced (especially the Hidden Rain logically had advanced cyborg technology to make the Paths), it's just that it was rarely applied.

Orochimaru's labs alone must contain a treasure trove of information, even though most of them were overrun and possibly destroyed. People other than Katasuke could've found such stuff and assembled new technologies.

We also know the Hidden Sand had advanced puppetry (to the point they could modify humans with puppet techniques), technology not shared by anyone else.
