Those weren't innovations, those were solutions in search of a problem. Probably contributed to their discontinuation. Also, what "innovation" of the past 20 years has been truly innovative, life-changing, and a net positive for humanity? Pretty much everything that has come out of Silicon Valley has been at best neutral for society (creating new markets and revenue for businesses aren't a positive in my eyes).
We need to stop pulling the "stifling innovation" card. Not stifling innovation has led us to society's cancerous relationship with technology.
