Want to know how long until pilotless planes? Simple formula.

Think of your own FMC. Let the number of years its been in operation = X. Let the number of times computing power that would be required for that FMC to fly without you = Y.

Multiply X times Y and divide by two for Moore' Law = Years to all airliners don't need you.

For example, I predict that a 737 will safely fly itself in the year 15520 AD.
