We don't know in this specific instance, but generally this is just fundamentally not true. You're way over-estimating the abilities of computers and way under-estimating the complexity of these systems.

I haven't been down voting your comments, but if I had to guess as to why other people are, it's because comments like this are typical of a certain kind of arrogance. I think we've all had that moment where we think "what, that sounds easy!" about someone else's problems, only to realise when we try to solve it ourselves we're suddenly confronted with that problem's true complexity. These are very smart people working on these problems, and your comments come across as if you're suggesting they've been negligent–while that could be true, it wouldn't be my first guess. Rocket science is hard, and things go wrong, and no amount of computing can change that.
