CAMBRIDGE, MASSACHUSETTS - At the end of 2021, five of our expert contributors - Calum Chace, Gaurav Chandra, Gil Press, Kirk Borne, and Ben Armour - took a look at key trends in artificial intelligence (AI) and machine learning (ML) in 2021, and offered their predictions on what 2022 might look like in terms of AI and ML applications in longevity, health and wellness, robotics, the Internet of Things (IoT), 3D printing, quantum computing, healthcare data, deep learning (DL), and AI-powered vaccine development and other medical treatments.

As we enter the final quarter of 2022, it is now time to take a look back and see how well these predictions turned out, whether they were on target, off the mark, somewhere in the middle, or still yet to be determined. In some cases, such as the metaverse, progress has been slow in 2022 and some of the enthusiasm that was noticeable at the end of 2021 has since faded away, but the metaverse is still likely to be impactful sooner ra
