> Why hasn't there been a minimal-boilerplate language and framework and programming environment?

There are? For example, rails has had boilerplate generation commands for a couple of decades.

There's boilerplate in Rails too. We move the goal posts for what we define as boilerplate as we better explore and solve a class of problems.

What boilerplate is there in rails?

html is like 90% boilerplate, and so .html.erb in rails is mostly boilerplate.

		We have the component architecture pattern to reduce the amount of html we have to write. If you’re duplicating html element in every page, that’s mostly on you. There’s a reason every template language have include statement. That’s a problem that’s been solved for ages.

Generating boilerplate is the worst of both worlds. The point is to not need so much of it.
