I would like to believe something in the medical field, but my guess:

Books/movies/TV shows/video games personalized for each reader/viewer/player

I'm still waiting for an "anti-microwave oven" that chills my can of beverage from room temperature to 33 degrees F in a few seconds (instead of putting it in the freezer for 45 minutes (or fridge for 5 hours) like I do now)

Hack-Man's 2023 predictions:

• There will be a death in space, causing all nations/companies to double their safety measures and delay further manned launches (China and Russia will be the only entities to launch humans for the rest of the year)
• Waymo will slowly expand SDV service; no other company will come close
• There will be 1 or 2 SDV deaths in 2023 (1 from a citizen driving a Tesla in self-driving mode; if a 2nd, it will not be Tesla or Waymo)
• Consumers will increasingly demand more privacy
• LastPass will announce another data breech (their 3rd in the last few years)
• The US House of Representatives will keep any positive legislature from becoming law
• China will relax CRISPR restrictions, sparking a global outrage
• Third world nations in Africa will start to get a much higher standard of living thanks to cheap/free satellite internet
• Hulu will either declare bankruptcy or get bought out, as consumers gravitate towards Netflix, Amazon Prime Video, Disney+, YoutubeTV, HBO+, and one new entry into the video streaming market
• One of the major grocery chains (Kroger, SuperValu, Ahold Delhaize, Albertsons) will either declare bankruptcy or get bought out, as consumers gravitate further towards online grocery delivery
• We will see a lot more walls, mirrors, windows with paper-thin OLED display tech surfaces, many with touch capability
• Mice will live longer (since longevity studies won't be done on humans yet)
• Biometric data will power more wearables
• No Next-Gen nuclear reactors will be built (or even in the planning stages) in the US
• 5% to 10% increase in battery efficiency will spark rise in solar power installation
• Work will restart on the Jeddah Tower; it won't be completed in 2023 but will nonetheless pass Burj Khalifa as the tallest man-made structure before the end of the year
• No substantial breakthroughs in Brain Machine Interface in 2023
• Nano-medicine to treat chronic illnesses
• By December, 10% of fast food "meat" sales will be veggie
• Clean Meat will drop in price, but not enough to the point where it is widely available in most grocery stores or restaurants
• Apolong driverless buses will be in regular use in China
• Google's Quantum Computer will pass a milestone where fewer people will doubt it
• GPT-4 will be jaw-dropping
• 2 dead musicians will release "new" songs (written by AI, based on their past library of work)
• Google Home will start selling a Google Assistant that follows you from room to room
• Tech companies (mostly Amazon, Apple, and Google) will expand and buy up medical data companies
• Meta will spin off one or more of: Facebook, WhatsApp, Instrgram, Oculus, Messenger
• An F5 hurricane will reach the shore of the southeast US
• California will have record-breaking wildfires
• Google will announce something huge--something that isn't on anyone's radar (i.e.: there were no /r/Futurology posts about it in 2022)
• More than 1,000 homes will be 3D printed
• Google will buy one or more small companies (maybe VMware from Dell) in an attempt to catch up to Amazon's AWS and Microsoft's Cloud
• A $1,000 computer will have the processing power of the human brain (not the intelligence, but the number of cycles)

Is this true? Wiki tells me he extended it until 2019 (not infinity) and since then the law has expired instead of being re-re-extended:

> In May 2011, President Barack Obama signed the PATRIOT Sunset Extensions Act of 2011, which extended three provisions. These provisions were modified and extended until 2019 by the USA Freedom Act, passed in 2015. In 2020, efforts to extend the provisions were not passed by the House of Representatives, and as such, the law has expired

Thanks for reminding me of one of the greatest sections of a good book

Sipping her champagne Kirsty Fantori, the star demolition engineer, started programming the nebulon missile. It had to explode at just the right moment to trigger off the reaction in the star’s core which would push it into supernova stage. A star in supernova would light up the entire galaxy for over a month, giving off more energy than the Earth’s sun could in ten billion years. It would be a hell of a bang.

One undetected bug in Fantozi’s programming could ruin everything. Not only did she have to push the star into supernova, she had to time it so the light from the explosion would reach Earth at exactly the right moment. The right moment was the same moment as the light from the other one hundred and twenty-seven supergiants, which were also being induced into supernovae, reached Earth.

For anyone living on Earth the result would be mindfizzlingly spectacular. One hundred and twenty-eight stars would appear to go supernova simultaneously, burning with such ferocity they would be visible even in daylight.

And the hundred and twenty-eight supernovae would spell out a message.

And this would be the message:

‘COKE ADDS LIFE!’

For five whole weeks, wherever you were on Earth, the huge tattoo would be branded across the day and night skies. Honeymooners in Hawaii would stand on the peak of Mauna Kca, gazing at sunsets stamped with the slogan. Commuters in London, stuck in traffic jams, would peer through the grey drizzle and gape at the Cola constellation. The few primitive tribes still untouched by civilization in the jungles of South America would look up at the heavens, and certainly not think about drinking Pepsi.

The cost of this single, three-word ad in star writing across the universe would amount to the entire military budget of the USA for the whole of history.

So, ridiculous though it was, it was still a marginally more sensible way of blowing trillions of Dollarpounds.

And, the Coke executives were assured by the advertising executives at Saachi, Saachi, Saachi, Saachi, Saachi and Saachi, it would put an end to the Cola war forever. Guaranteed.

Pepsi would be buried.

OK, it wasn’t wonderful, ecologically speaking. OK, it involved the destruction of a hundred and twenty-eight stars, which otherwise would have lasted another twenty-five million years or so. OK, when the stars exploded they would gobble up three or four planets in each of their solar systems. And, OK, the resulting radiation would last long past the lifetime of our own planet.

But it sure as hell would sell a lot of cans of a certain fizzy drink.
