What stood out to me more than this particular project is the visible acceleration of a phenomenon many of us could foresee, especially over the last year or so: people can build a version of the same idea faster than ever.
After like 10 minutes of searching I found multiple similar swift projects (most of them are just a couple of weeks or months old):
https://github.com/tdeverx/contained-app https://github.com/nico81/iContainer https://github.com/wouterdebie/davit https://github.com/Augani/dory https://github.com/tofa84/berth https://github.com/erdaltoprak/ContainerUtility https://github.com/andrew-waters/orchard
There were more if you include ones with fewer GitHub stars, CLI-only, non-Swift etc. but you get the idea.
People will increasingly be able to build their own version of the software they want. As that happens the value of someone else's decreases. The era of hyper-personal software is coming.
