Finished watching. WELL WORTH the time spent.
I found no factual errors in the doco - and had to completely agree with the viewpoints expressed.
If you use 'apps' on a cell phone, do banking or transactions digitally - you should REALLY reconside.
And the idea that 'crypto' currencies are 'secure' because they use 'blockchain' - YGBSM - no way. Nor are 'secure' https connections actually secure. Encrypted email/files ... fuggetaboutit.
On cell phones - think about it. Their Operating Systems are AT LEAST ONE GIGABYTE in size. With that many lines of 'code' - you can be absolutely CERTAIN that they really DO NOT have any security. There will be holes and backdoors galore. You can't have that many bits of code without any errors, intended or not, that can be easily exploited.
Take it from someone who has been there, dun that.
Remember DEC - Digital Equipment Corporation, and the VAX computer systems? Pretty sophisticated at the time, and pretty security conscious. I found a MAJOR flaw that was easily exploited to give me unrestricted system administrator privileges. And I don't really consider myself to be a 'hacker' - there are folks out there, especially in the gubnuts, that make what I do/did look like child's play.
Take a look at the 'Vault 7' archives on Wikileaks (if you can still find it) and you will see why you should NEVER consider your personal computer or cell phone to be 'secure'. They are not - not by a million miles.
