I'd say it depends on what you are trying to do. If it is simple device control and media playing and other stuff, then all you need is to update [dashboards](https://www.home-assistant.io/dashboards/) when you add/move devices and the users will find it pretty easy and straightforward. My parents are not extremely tech savvy but they find Home Assistant easy to use when I make the dashboards thoughtfully.

Making automations and scripts is getting easier every update, but it has a small learning curve as the logic can get complex and you sometimes need to know details like entity IDs or raw states. And there are some simple missing features that some people are very used to. Home Assistant is improving that sort of thing constantly, but sometimes the device APIs do not allow all functionality without the OEM apps.

For example, the two biggest camera-related things that are missing in my opinion is that the camera viewer does not allow zoom or two way talk. It uses the native browser media player, and on both a Samsung tablet and all iOS devices, this means that you cannot zoom and pan around the image. This is obviously not an issue if you embed a dashboard such as Frigate into the HA UI, which IIRC supports both two way talk and zoom. But YMMV.
