But you still have all maintenance related problems? How do you upgrade a hard disk or memory, go to their home? What happens if their home net is down or slow, no one can visit the site? Back in the days I was running a few web servers from my office directly, and it's a lot of extra work that is just not worth it.
There's still plenty of room for paid hosting services. But this lowers the bar in a major way.
If their home network is down, hopefully their office network isn't, or their business partners' networks aren't.
Also, these kinds of applications are practically begging for mesh networks. So what it means for a home network to be "down" could change a lot in the coming years.
The Internet is breaking all the time anyway. Every day at least one of the bigger / more important sites I visit has a temporary problem with something. Three days a week HN keeps returning CloudFlare errors to me. Even Facebook has some issues that break it every other week. The world isn't ending because of this, and it isn't going to end because the site I co-host with my other friend is down for the night.
As you grow to the point where close-to-perfect reliability matters, you'll be able to afford to get someone do handle the hosting for you, just like you do today.
Not denying you get these issues or errors with sites. But how come I never seem to have any issues with major sites. I do see cloudflare stuff. But never for a top 1000 site.
