stockblues  Suresh's move to develop the optical interposer began in 2017. POET hit  a low of $1.75 that year so I think instead of slamming Suresh you should be thanking him for how far he has come in developing this platform. 

He recognised the need for industry to have a  low cost and efficient platform that can be ramped far quicker than existing technologies with unparalleled design flexibility.

I would never suggest that you sell your shares. I would however suggest that you try to understand the magnitude of those accomplishments and recognize how this platform will drive tthe commercial success of this company.
