I don't care how the financial markets work - I trust my 401k to pay for my retirement.
Life is far too short for me to want to know about things that don't interest me. One of the points of an advanced society is that we can pay people to do things for us.
People shouldn't have to second guess every professional service they use. Maybe it's time to add legal guarantees to the cloud?
So... Lets make it illegal for a site to lose your data by being shut down by the FBI? Seriously though, is it really a good idea to make more (artificial and unsolvable) problems for cloud service providers to worry about?
Where do you draw the line? Do you make your own yoghurt? What about milk your own cows? I very much doubt you do that. My time is valuable enough that I'm comfortable paying people to do these things for me.
If person A offers a service to person B, there needs to be some level of trust and expectation. In this instance, the government is responsible for destroying people's assets and I hope they get sued to oblivion for screwing up. Other times, companies are at fault.
Gotta love the Libertarian mindset that appears to prevail here. Sheesh.
I think it's still worthwhile to have a superficial understanding of the services you buy, as this allows you to maximize the value of your dollar and avoid getting fleeced.
