Not knowing stuff is fine, it's pretending you do when you don't that's obnoxious.
Fractal hasn't really said much though. We don't know if it's going to specifically be official Neural Amp Modeling tech or some other proprietary tech Fractal is coming up with on their own.
Either way I think the implication is that the next gen Fractal stuff will have both traditional white box modeling where the actual schematic is known and emulated at the component and signal path level in conjunction with measurements of the real deal examples, as well as black box amp profiling where you just put an amp through some kind of analyzer that sends signals into it and measures what comes out, and builds some kind of amp profile based on that.
