Here’s what our science and technology correspondents are keeping an eye out for next year
will make its first test flight. Crucially, that test will take place over land—specifically, Edwards Air Force Base in California. Concorde, the world’s first and only commercial supersonic airliner, was not allowed to travel faster than sound when flying over land. The-59’s sonic boom is expected to be just one-eighth as loud as Concorde’s. At 75 perceived decibels, it will be equivalent to a distant thunderstorm—more of a sonic “thump”.
But when will such machines arrive? One measure of a quantum computer’s capability is its number of qubits. A Chinese team has built a computer with 66 qubits., an American firm, hopes to hit 433 qubits in 2022 and 1,000 by 2023. But existing machines have a fatal flaw: the delicate quantum states on which they depend last for just a fraction of a second. Fixing that will take years.
The best known is Miquela Sousa, or “Lil Miquela”, a fictitious Brazilian-American 19-year-old with 3m Instagram followers. With $15bn expected to be spent on influencer marketing in 2022, virtual influencers are proliferating. Aya Stellar—an interstellar traveller crafted by Cosmiq Universe, a marketing agency—will land on Earth in February. She has already released a song on YouTube.
In 2022 Neuralink hopes to test its device in humans, to enable people who are paralysed to operate a computer. Another firm, Synchron, has already received approval from American regulators to begin human trials of a similar device. Its “minimally invasive” neural prosthetic is inserted into the brain via blood vessels in the neck.
It is expected to be joined by a handful of other firms in 2022. In the coming year an Israeli startup, SuperMeat, expects to win approval for commercial sales of cultivated chicken burgers, grown for $10 a pop—down from $2,500 in 2018, the company says. Finless Foods, based in California, hopes for approval to sell cultivated bluefin tuna, grown for $440 a kilogram—down from $660,000 in 2017. Bacon, turkey and other cultivated meats are in the pipeline.
