All this would be way more interesting if it actually helped to demonstrate a novel mathematical fact. Right now it's more like notational play.

The boat seems to go faster with the sails on the wrong side (back winded), that doesn't make a ton of physical sense to me

Besides the legal requirement, the reason these companies go public is often to provide liquidity for early investors or employees. So they do want to have as good of a margin story that they can, at least in terms of unit margin.

> Just serialize stuff to text if somebody wants to "edit" and then parse it back when they are done. What happens to the text in between of course is the programmer's problem.

I think that's working against the way that a lot of people write code.

You need things like syntax highlighting and code completion even while typing something like "my_var = " on a line. A normal parser doesn't work here, and bailing out to make it the programmer's problem leaves the programmer with a lot of work
