It's unlikely that this is the only device in existence that has a power side-channel. And attacks get better with time.
There are lots of engineers who go "nah, too many conjunctions, this will NEVER happen" when designing some hardware until reality hits them over the head.
Also, the standard for cryptographic security tends to be "better than brute force". 65 minutes to extract a key is orders of magnitude better.

That's why certain agencies prioritizing collection over real-time cracking. Collect first, worry about the content later. An adversary just need 65 minutes of footage taken at some point - and we live in an age where there are plenty of devices that can passively capture w/ their cameras. 65 minutes is pretty bad. That's several orders of magnitude less than it takes to crack password hashes.
