My reputation for gullibility precedes me! 
Apologies to Abram for derailing a serious and interesting thread.
The authors of the Nature article are associated with the German branch of a company called Audactic. Restoring speech intelligibility for hearing aid users with deep learning | Scientific Reports (link to author information for paper)
I did a Bing/ChatGPT search to see what hearing aid company Audactic might be associated with and got the following answer, which I’ve edited for brevity:
I’m sorry, I could not find any information about a German company called Audactic that is associated with hearing aids. The only Audactic I found is a Swiss company that develops systems to intelligently modify sound using artificial intelligence¹. They claim to provide a solution for millions of hearing aids users, but they do not seem to be a hearing aid company themselves¹.

Interesting. Sonova is a Swiss-based company (the parent company of Phonak). Research has to be world-class to get published in Nature. Interesting that they expect to get stuff that now requires a laptop (not even a smartphone!) to run on HA’s “within a few years.”
