I’ve had the same problem with HeliBoard learning garbage. I just changed my settings though, and I think it should help:

1. Open HeliBoard settings
2. Open Text correction settings
3. Scroll all the way to the bottom, and turn off “Add words to personal dictionary”

If you scroll all the way to the top again, you can manually manage the personal dictionary, including adding words you do want, and deleting any junk that was added by mistake, before switching that setting off.

I think to be fair, you’ve got to compare his before and after, rather than comparing him to anyone else.

I certainly wouldn’t say he looks young, but I think he’s on a better trajectory.

Someone testing on themselves is how we learned what causes and how to treat ulcers (the researcher earned a Nobel prize for giving himself an ulcer, and then treating it), among other things.

Controlled trials are great, but research has to start somewhere.
