These are personal thoughts across a wide range of topics, I’m not speaking for my current or past employers in this post. As well as the video, there’s a long podcast where I discuss them with Mik Kersten.

While it’s sadly premature to say that the survey took place at the end of the COVID-19 pandemic (though we can all hope), it took place at a time when restrictions were loosening: we were starting to go out in public, have parties, and in some cases even attend in-person conferences. We’re not sure what that means.
