I think the "potential" realistic indications and market/commercial numbers, along with patent life, more than support a $5b buy out personally, at some point down the road. Just not today.

Hopefully there is time, finances, further study success, and partnering structure arrangements (milestones) coming that will allow that to occur if properly negotiated and structured with "on the come" ("prove it") provisions and value propositions.

There is no guarantee of anything ever materializing though, of course. Soooo, there's that too, of course ...
