Most open source projects are abandoned because the author never finds enough time to work on it or can't muster the focus and attention needed.
It is not true that there is "lack" of human investment in the creation of this. If anything, I spent the last two weeks glued to the screen most of the time, to a degree I have never experienced before, building out all the different areas that lead to this release.
I will not mention the monetary investment because it's not the type that matters here.
Attention, which is arguably the most scarce form of investment, was invested in ample amounts.
