The Muppets are clearly going downhill and may become extinct. Because Disney’s Muppets stopped making YouTube videos and stopped making  episodes of Muppets Now. And all what they basically do is social media. And who knows whether Dave Goelz, will still perform with The Muppets. I don’t know? Frankly I’d rather see him quit than to perform the characters that aren’t what Jim Henson had known them. And since Dave is around 75 years old and maybe he wants to retire.
