It makes me think of the early days of cinema. It took a while for things to fall into place. Even things that are considered masterpieces like "Metropolis" are a bit weird in contemporary terms; set pieces go on way too long, serious moments sometimes come off as comical, actors stare into the camera, etc. It's not hard to imagine that the non-masterpiece run of the mill stuff was nigh unwatchable in today's terms.
So "Nothing Forever" isn't funny now but I'd be surprised if something like it is more than 5 years away from watchable.
I think this should be used more often. In modern film it's mostly used for forth wall breaking as a cheap joke, but the acclaimed Japanese director Yasujirō Ozu often used the technique for a kind of "VR" effect, to make the viewer feel like they're present in the scene. The characters address the camera directly but they don't show any awareness of the camera. If you haven't already, I recommend watching "Tokyo Story" to see how it's done. It places highly on many "best movies of all time" lists, and despite the slow pacing and lack of action I found it surprisingly compelling.
