I feel Apple is solving a problem that doesn't exist. How many times did you on purpose ignore a caller only to immediately check voice mail and find out you really wished you had taken the call?
All the time.
For example, I may not recognize the number and worry it's a spammer.
Or it's someone I know, but I only want to talk if it's important.
But I guess it will be a great tool for parents getting the kids to pick up. Just say "DAD IS IN THE HOSPITAL" and wait for them to pick up.
Will only work once though, but still a huge success for some parent/kid relations.
Sure, if "my mom is a liar" is a "success".
