A trip to the International Space Station

It’s the year 2040, and you decide to go on holiday. While you’re still sitting in your smart home, a digital avatar will appear as your travel agent, predicts Caroline Bremner, head of travel research at Euromonitor International, in a recent paper entitled Travel 2040. The avatar will use “emotion recognition software to match individual preferences with travel opportunities”. You’ll even get a virtual taster of what to expect before committing. The effects on climate change, energy conservation and waste prevention will all be factors in your decision.

So, you’ve decided, and told the digital travel agent where you want to go, and the day of departure rolls around. Your bags are packed and it’s time to leave for the airport. “You hop on a four-passenger air taxi over the city to the airport where a supersonic aircraft is waiting to whisk you in a few hours across oceans and continents.” At least, that’s the vision of French aerospace and defence group Thales.

But first you have to get through the all-too-familiar rigmarole of airport security. You may still be required to carry a physical passport for legal reasons, futurist Ray Hammond predicted in a report last year, called The World in 2040, for Allianz Partners. But otherwise, “by 2040, your face will be your passport and your boarding pass”, with iris scans and finger-print recognition systems there as back-ups. And there will be no waiting while the person in front of you dives into their bags for the laptop they forgot to take out. “Waiting times will be substantially reduced.” Once through, artificially intelligent (AI) digital assistants will direct you to airport lounges, bars, restaurants and shops.

Alexa is your pilot today

Beyond the gate, “your ‘pilot’ might be in the cockpit – but might also be on the ground supervising the flight through data and information in the cloud”, says Thales. As you recline in your seat and close your eyes, you will hear “only a muffled sonic boom” as the plane breaks the sound barrier.

European aircraft maker Airbus offers a slightly different take. It sees the near future of flight as being a low-emissions one. If the cost of hydrogen were to come down (possibly with government investment), “zero-emission aviation [would be] commercially viable in the 2030s”, says Glenn Llewellyn, vice-president of zero-emissions technology at Airbus. Either way, aeroplanes will be smaller and, in the case of supersonic jets, much faster than today. In the air, economy passengers will put on their virtual -reality headsets (see page 42), while premium passengers will relax in multi-sensory “pods”, says Hammond.

You’ve landed and left the airport. Thanks to augmented reality (AR), whereby information is overlaid on a real-world view on your smartphone or the lenses on your sunglasses, finding your way at your destination is a breeze. Even if you do need to ask for directions, translation apps and earpieces will make foreign languages intelligible – something of the latter already exists in the form of Google Pixel Buds. At the hotel, you “will be greeted by an AI avatar concierge”, says Bremner. That’s not far-fetched. The original Henn na hotel in Nagasaki has employed robot workers (above) since 2015, although it reportedly had to fire half of them for being lousy at their jobs. Still, by 2040 technology will have moved on. Your bags will be delivered to your room and a voice-activated digital assistant will be on hand, much like Amazon’s Alexa is now, to do everything from turning on the TV to running you a bath.

The sky is no limit

And there may be no need to stick to holidaying on Earth. Next Saturday, Elon Musk’s SpaceX is scheduled to carry out the first commercial mission with Nasa to carry astronauts to the International Space Station (ISS) for a standard crew rotation. If SpaceX can carry astronauts, then why not tourists? SpaceX announced in March that it was aiming to send three tourists to the ISS by late next year for a ten-day stay and, according to The New York Times, one person has already signed up for the ride, at a cost thought to be around $55m. A “space hotel” is also on the cards. The Gateway Foundation, a private company, is planning to build one as part of its Von Braun Rotating Space Station sometime over the next decade.
