But that's a small sacrifice to be cancer-free with everything else functioning. I always was one to think much and speak little anyway...and one could always be worse off like this ALS fellow. Told my doctors to get the voicebox from the next idiot rock singer that offs himself because there's been a lot of them. Waste not...
Yes, this device is a wonderful achievement and I believe that as time goes on we will make even further great advances in technological communications for those who have lost the biological means.
I like your idea of harvesting a deceased rock singer's voicebox. Knowing the generally foolish things that have emerged from those voiceboxes in their original owners, having one in your possession would be a substantial improvement in the quality and sanity of its output. :-)
