Smell the coffee!

Little gets the attention he does because he has a game changing technology, the support of Andy Grove, one of Intel's founders, and is a natural communicator. You're right about other people having similar technology: it's an idea whose time has come. But it is Little who in just a few months got over 10,000 people to submit a voice sample.

Little's approach enables rapid, free diagnoses. But it offers other advantages as well. I suspect that used in addition to the normal doctor-led diagnostic process it will reduce the number of misdiagnoses. It enables symptom measurement which, in turn, offers the possibility of mass trials, reporting quickly.

If I were to select those initiatives in the last 5 years which were most likely to translate into an improvement in the lives of medium term PwPs, I would choose (in no order):
Little, Parkinson's voice initiative;
Brin, 23andMe, mass genetic testing;
Alberts, forced exercise;
Jannetta, peduncle compression.
