there is one big problem with computing systems we are building currently. focus is on sandboxing, making programs and apps safe and isolated.
so its all more safe, whats the issue?

here it is:
the more safe and sandboxed the program is, the less you care what its doing
you are more likely to allocate resources to programs you have no idea what they are doing

"sandboxing" may be the trojan javascript turned out to be. not because sandboxing is inherently bad, its because of the psychological effect it causes: you dont care anymore
