What's the current outlook for nanotechnology? Technically speaking, do we get Star Trek replicators soon, or is that still a 25+ year thing (https://www.xkcd.com/678/)? Politically, how do regulations, industry, and patents look? Socially, is it generally viewed as positive or negative these days?

The ultimate dream in nanotechnology is a molecular assembler (atomic 3D printer) on every desktop, with a widespread community of hardware designers/developers analogous to open source software today. You'll be able to, say, download files to build a new car from GitHub. Hackaday has a good writeup (https://hackaday.com/2018/02/27/can-open-source-hardware-be-like-open-source-software/). Suppose that someone finally figures out how to build such a molecular assembler. Chances are it'll be patent-encumbered and NDA'd. How can we from here to there?

Integrated circuits, solar panels, and GMOs are some pretty big results in nanotech these days. What are some future benefits we can look forward to that help justify further research to non-techies?
