I was imagining bespoke situated software for planning my five-year old's birthday party.

Someone countered that that was a niche use case.

But it's not a niche use case!

Every parent in the world will have this use case at some point.

The only reason it seems niche is because it's not viable in our current laws of physics.

It's not possible to build a single one-size-fits-all five-year-old-birthday-planning app.

Even if it were, It's not possible to distribute it.

Users have the need at one specific time in their life and never again.

For the users to use the app, they'd have to know it exists, think to use it at that moment, and do the high friction steps to install and onboard.

That would require massive amounts of marketing to accomplish… more marketing than the value of the app supports.

But that's a limitation of today's laws of physics, not a lack of importance of the human needs.

The universe of one-size-fits-all, expensive-to-distribute software required by todays laws of physics simply cannot cover all of the possibility space of useful software.

There are millions of these use cases that are human needs but cannot be addressed by software today in our current laws of physics.

We need new physics!
