No I've accepted that our current tools and therapy methods don't work.  I've kept the door open to future advancement in technology to come up with the solution.  Perhaps we need AI to do the research for us and I will follow the news on this.  I'm not saying that it is an unsolvable problem, but I'm logical enough to understand that it likely wont happen in my lifetime so ive accepted that and try to live my life normally.   If you feel you need to fight internet battles to get closer to making your stutter magically go away tomorrow then thats your prerogative.
