I was thinking about restricting the comparison to...
companies that are attempting to accomplish the same goals that Torvec has been working towards. Please don't confuse the non-core shareholders' goals with the Torvec's goals.
Anyway, it won't be until we see a competitor achieve these goals first that we will have to announce some sort of failure.
Here is a competitor that is getting close with one of the (eight) Torvec technologies.
We might want to keep an eye on this progress as it seems to be moving forward.
