Every quarter Brent Ozar publishes some data from his SQL ConstantCare® service. This is a service where companies contract with Brent to install a service on their instance, collect data, and give them simple, short daily emails on things they should check. It's a good service for companies who don't employ skilled DBAs and may relay on a developer or sysadmin to manage a SQL Server instance. While this is a self-selecting group of organizations, across his 3,100+ monitored servers, there are likely trends that could apply to the world of SQL Servers in general. After all, for every gung-ho, let's-upgrade DBA, there's probably a sysadmin with a similar mindset.
In any case, the summer 2023 report form Brent shows that SQL Server 2022 adoption has slowed. His report is down, though I doubt anyone downgraded. Perhaps someone was testing and added a 2022 server in the spring they removed. Or maybe they tried 2022 and then went to the cloud. He does show 2019 growing and 2016 shrinking, which dovetails with what I see from my memory of various questions at SQL Server Central. I see people asking about moving from older versions to 2019 much more than 2022.
I wonder what that is? Brent thinks this is because people standardized on 2019 installs and haven't moved to 2022. So anyone adding new instances likely uses an image/setup/process for 2019. That matches with a few of my customers, who haven't had some of their install or security processes updated and are still adding 2019 instances. I think that's short-sighted as 2019 is 4 years old, but I also understand that people get busy and updating anything for a new version isn't a priority.
There have also been some problems with updates, and Brent thinks companies are skipping 2022. I don't know, but I do wonder what you think about your estate and how things are changing. I assume if you are still running 2014- at this point, you'll just live with the server as long as you can. I hope you're at least on a VM so you can restore quickly if there are issues (assuming you back up VMs).
If you run 2016/2017, are you looking to upgrade? Considering 2022 or stick with 2019? Or kick the can and hope that SQL Server 2024 or 2025 will be better? Actually, take a guess as well on the next release date. I'll take a page from Brent and run a contest for you to guess the next release date.
