IOS new architechture will be more vulnerable?

[Joe Maimon <jmaimon () ttec com>]

quotes from wired interview with Mike Lynn

"
WN: So this new version of the operating system that they're coming out 
with, that's in beta testing.

Lynn: It's actually a better architecture ... but it will be less 
secure.... That's why I felt it was important to make the point now 
rather than sweep it under the rug. I think it's something that we can 
fix....

"

But at the same time, now that I think they already are, I will say it's 
not as bad as you probably think it is. Not yet ... because the version 
that makes this an unstoppable critical problem is not out yet.

What exactly does this mean?
