We haven't noticed any people from Krypton flying around our skies but we are certainly closer to the world depicted in The Jetsons.

This cartoon was remarkably good at predicting the future.

We now have video calls; flat screen televisions; electronic sliding doors; food vending machines; electronic toothbrushes; moving walkways and many devices first seen in The Jetsons.

And just like our society, everyone on The Jetsons complains of the exhausting work they have to do. First-world problems! Despite this progress, we are yet to match the way George travels to work. But...

The technology in drones has been progressing at a rapid rate.

17 countries are already delivering parcels as we speak and 13 are using drones for medical deliveries.

New Zealand had the first pizza delivery by drone (I am not sure if a pizza is counted as a parcel or, to many, it may be medicine.)

In Germany, industrial parts and pizzas are being delivered by drones - presumably by separate ones. Coffee (yes coffee) is being delivered in Dubai.

In the UK, you can have your new phone delivered by drone.

Many people speak of regional drone deliveries but they will initially be used in highly congested areas. Drones have a complex mathematical formula of weight and range and charge.

Drones need to be as light as possible.

To fly further distances, a drone relies on the amount of energy available.

That seems easy - increase the size of the battery.

When you increase the size of the battery, you increase the weight so you lose some of the gain.

Increase the battery some more?

Sure, then you need larger motors which, you guessed it, increases the weight and you need more battery and...you get the picture.

The real sweet spot is a drone that travels in a city like Sydney where traffic is a nightmare.

Sending a delivery drone to a regional location where there is good road infrastructure doesn't make a lot of sense.

The next step is transporting humans.

It won't be long before you hail your taxi and a drone lands on a skypad near you.

Melbourne will start a trial next year of an app-hailed Uber service. Forget new motorways or tunnels - this will revolutionise transport.

A one-hour trip from Melbourne's CBD to the airport will take just ten minutes by air. The initial trials will be with piloted drones.

The long-term view is that you will hail a driverless drone and then board an electric air taxi (not sure about the acronym EAT) and arrive safely at your destination.

George Jetson - move over. Here we come!
