The security nightmare is reduced by a lot, thanks to Linux being a lot more safe system. Of course the occasional very old security issues get found, but those are only old if some swifty hacker found out and didn't disclose it publicly, or had to wait for years to be solved.

I tried it to do some research recalls, like set it up for doing very specific things and I found it filled my hard drive pretty fast with screenshots. It's probably a good idea if you can turn it on and off like this one and be careful, but it likely still needs polishing. That was when it was first out.

Python? This will require “specialized hardware” just due to the interpreter overhead taking continuous screenshots of everything you do and indexing/storing them. Why bother implementing something like this using an interpreted language??
