Let us know when they have clinical results in a subject(s) that can communicate in a bit more detail than mice. The authors say the trials may start as early as 2017, so I don't expect a useful answer before 2020, maybe 2019 at the earliest.
I'd love to be wrong but I've seen too many promising ideas die in clinical trials. Let's hope for the best.
This is from March 2015. It's an interesting technique and I would be interested to know if they have further results.
