My problem is:

This sounds promising
As have so many things before
I'll believe it when I see it.

Great strides have been made,
but we are missing Something here.

:( A/L

==============
I'm in 100% agreement with you: positive article after article from some
of the most reputable universities and labs around the country and the world ...
and yet, as you say, something is clearly missing. "I'll believe it when I
see it" sure does sound to me like the perfect response.
I guess I actually put the articles up for your perusal with a kind of "as IF
they were truly promising" frame of mind. SOMEthing's gotta give. I can't
believe there'll NEVER be any breakthroughs towards progress! But I sure
do hear your point!

Thanks -
