In the spirit of the last couple of years, we review developments in what we have identified as the key technology drivers for the 2020s in the world of databases, data management and AI. We are looking back at 2021, trying to identify patterns that will shape 2022. Today we pick up from where we started with part one of our review, to cover AI and knowledge graphs. In principle, we try to approach AI holistically. To take into account positives and negatives, from the shiny to the mundane, and from hardware to software.
