Don't think the dialogue would ever end with these kind of guys, their bosses will decrease their short positions surely over time (rather sooner than later I think), but as with every stock as long as there are any shares short or people wanting to buy our shares cheaper, we will hear some funny arguments...
Just to say at no price point, commercialisation stage or profitability level will shareholders of any company ever be completely free of these kind of guys...they are just part of the game and will always be...
Case in point, one would think the more validations we get, the more sophisticated the arguments of shorts would become, in which case it would actually serve us to educate or convince them BUT as we observed frequently over the past year ironically the exact opposite is the case: The more validations we have seen, the more outrageous (eg. "Microsoft, Dell, Pearson, Novarad don't really know the tech they are collaborating with") their statements have become!
Myself, for example, I used to admittedly research if they had a point when they posted something plausible, but by now due to the aforementioned observation, I just find them silly and annoying and best left on ignore.
