Here's my take...once the genie is out of the bottle...and recognized for what it is...that being a Platform Technology with a $#!Tload of indications...don't see much of anything holding us back...that being said...with all the stories you've heard about shelving live-saving drugs...OVER-hauling the medical system along with Big/small-minded pharma..hopefully, the status quo will bend to the entreaty of a public that is tired of being kept alive...to ensure a revenue stream...healing is not in the best interest of big pharma...as steel houses are not in the best interest of the housing industry..(.author license here). Paradigm shifts have not been uncommon in this century...and societies, in general, want umbrella protection for their citizenry...so that dad's 401K... doesn't end up furnishing a house in the Hamptons.
