I noted the same things when I was going through burnout. I also noted that no one in my life used or even really knew about what I did. It felt like telling people I had a Canadian girlfriend. People are pretty sure I really do have a job but who knows what it is.

So not only is the physical aspect of the job missing, the produced artifacts of your labours don't exist in your community either. It is like leaving your community for 8+ hours a day.

Lastly, it is demonstrably ephemeral. Websites, apps, documents, spreadsheets, reports. It's all obsolete so fast that it can feel pointless having put so much effort in the first time.

I love software and I love working in competent teams and making cool stuff. But I think it needs to be balanced with doing real world things within your community.
