At first, an in-ear phone and language translator, while useful, might not seem compelling. But take things a bit further. This relies on a mini-computer and connection to the internet in the hearing aid. What if that allowed you to connect to Chat-GPT? Or future more powerful versions of it. That might be more compelling. Sci-fi has often envisioned cyborgs in the future. Maybe one day people will look back at stuff like this and think it was the first baby steps of that technology.
