Technologists talking to technologists.
They are not investors by nature as they all get well paid doing what they do so don't have the time or inclination to be investors.
The investors are disappointed that there has been no big news in conjunction with the presentations.
We wait for insiders to convert their warrants into shares and news of customers and partners and suppliers of lasers and start-ups of manufacturing in China and Suresh to drink his cup of tea and someone to put an end to Putin.
News could drop at any time of day or night.
My simple thoughts.
