This misses the case where the plausible solution space is much larger than could be explored by the smart people that have attempted to solve it in the past.

Also, a lot of times the enabling new technology or new customer behavior doesn't obviously solve the problem. So there may be new technology and/or behavior that make the problem solvable, but it's not obvious until you try to solve it. There is new technology and customer behaviors that make a whole slew of seemingly unrelated problems solvable now, and if I knew the mapping there, I wouldn't be posting here, I'd be running a company that solves the problems.
