IMO we are ways off from even being considered as a buyout target, give it 2 years and see where the company is at in terms of market penetration and technology adoption.
Don't forget any acquiring public company needs to justify to it's shareholders spending ~ $500M or $1B whatever the number is of their capital on an unproven zero revenue company is unrealistic.
Once the technology has gained market share and is generating positive cash flow then lets bring up the possibility, but right now is not the time.
FWIW, I do believe a buyout is the eventual end for this company. Poet Technologies the company will not live on for another 10 years but hopefully the technology lives on for much longer.
