Then it's reasonable to say we're not quite ready for the masses yet. Maybe there will be a time in future when people can use Bitcoin without understanding it, but that time isn't yet. Plus I'd still argue that even when that time does come, it's better for people to be able to tell what's going on at a technical level for the sake of overall transparency. Complacency isn't something we should encourage when it comes to a relatively new technology.
Making the technology easier to use won't necessarily make people's money any less easy to lose. Maybe the blockchain.info wallet service itself is secure enough, but if people come along thinking that all third party services that offer to store bitcoins online are just as secure, they're more likely to get burned. New users need to understand that it's not safe to assume that all the services they encounter will offer the same levels of protection.
As an analogy, just because car manufacturers can design cars that can parallel park all by themselves, it doesn't mean we should stop teaching new drivers how to do it yet, in case they find themselves in a car without that feature. Maybe that will change in future, but not yet. The same applies to Bitcoin for the time being. Unless you want the negative headlines to continue, it's better for users to have a basic understanding of how this all works.
