Ask HN: Whatever happened to JavaScript build tool Fez?

For a project that uses Typescript and some bundle/minify tooling I've tried most of the "2016" build tools (gulp, grunt, brunch, jake), but whaa.. what the hell people?

I miss the power of the traditional file-based build tool, similar to what Make does for sensible incremental builds (but ideally a variant that runs in node, as I want fast recompiles in watch mode by keeping js-code of the tools in memory).

In 2014, a project like this called Fez was launched here on HN: https://news.ycombinator.com/item?id=7090479.

Now, unfortunately, its website, its author's website and the main github repo seem to be offline. Any idea what happened?
