Potentially some of the feeling could come from the way articles are often times intentionally sensationalized to make it sound like THE CURE is right around the corner.
Some people may have their emotional happiness based on the need to feel that THE CURE is being worked on and is about to be delivered.
Other people may find it emotionally disappointing and draining to hear years after years about THE CURE being right around the corner but never to have it materialize.
Some people are pessimists and some people are optimists.
I personally am happy with small stepping stones. In addition, I like a balance of research towards THE CURE as well as research towards managing diabetes with the assumption there is no imminent cure.
I would not want to have all my hopes and all funding focused in one direction and under one roof. I like funding and research spread around. Some will show results and some will not. Some funding will be foolishly spent and some will not. Some funding will even be illegally stolen. Some research and funding will be spent on short term projects for management and some on long term research that will not yield fruit for time to come. Some funding should be spent on immediate patient management using what is not only currently available but what is practical for that patient.
IMHO the only approach which would be foolish would be to do nothing.
