If instead of switching from one factor to another they promoted multi-factor authentication, they'd relax constraints on each factor (ie. passwords easier to remember, biometrics cheap to implement).
Original article has two flaws with the number you quote. It's not 566TWh, it's 5.66TWh (that's the value advertised for yesterday as total energy), that's 2 orders of magnitude. And it's not "typically" since it's the accumulated value over the service lifetime. If you want to quote a typical value, you quote current power (in W, not Wh) and the website advertise it as 6.74 GWp (p for peak, the bullshit suffix used by the solar panel industry (should be 6.74 GWbs IMHO), so the actual value is even less), that's another 3 order of magnitude. I guess the actual numbers are less impressive...
Hackaday's maths are wrong, they build it on the assumption that a length of filament clearly shorter than two fingers width is 13cm long. Hackaday's news quality has been going down lately, I wonder why Slashdot is quoting them more and more.
Hopefully it doesn't end that bad: Mimic.
Yes, sure, go tell the people in Angola or the other dozen countries in Africa that have 30 years less to live than you on average that aging is a problem. Or maybe the OP was talking about 100% of the population of every country a typical north american high schooler ever heard about.
