> Is a better de-noisier algorithm in Adobe Lightroom worth $500 billion?

No.

But: a tool that allows me to de-noise some images, just by uploading a few samples and describing what I want to change, just might be? Even more so, possibly, if I can also upload a desired result and let the "AI" work on things until it matches that?

But also: cool, that saves me several hours per week! Not: oh, wow, that means I can get rid of this entire department...
