My understanding is that a lot of the slow progress from 1878 to the early 1900s was the “cinema tech stack” needing to become technically and economically viable.
To get good motion you need ~16 frames per second, which means each frame has to be exposed ~1/16 of a second, which in turn means you need stuff like sensitive film stock, lots of light, decent lenses. Then you need a camera that can move film in a way that is at a constant speed but also holds each frame perfectly still briefly, for a precise duration, and without any jitter/warping/etc. Then for economic viability you also need projection that’s bright and safe for a room, plus a practical way to duplicate film at scale.
The starting point for all of this was early photography (e.g. daguerreotypes in the 1830s–40s), which used rigid metal plates and multi-minute exposures in bright daylight.
For some forms of AI art (single images, short clips) the tech stack feels maybe mostly already there, while for others it doesn’t (how to turn short clips into a full-length movie). But maybe that’s just a lack of imagination, and we’ll look back and say something like: “they didn’t realize they needed BCI to really unlock AI art’s potential”.
What kind of single knob are you using?
I find the design below where ‘left-right’ controls temperature and ‘up-down’ controls flow intuitive and easy to use.
