It's possible that we get to a place where everyone cooks their own meal (vibe coded app), and only goes out to eat sometimes (official app store). Spreadsheets are the same, you can get a lot of milage, and most still buy and use closed source software.

Literally who?
The rest of us groan when we hear "DOWNLOAD OUR APP" or grocery stores that want you to install their spyware coupon app.
These days, nost apps are just data exflitrators, spyware portals, and surveillance pricing initiatives, wrapped up with a "FREE THINGY" wrapping.
