Why should humanity put so many resources towards improvements that no mere mortal can notice? It’s probably better to put the talent on other problems...
True if you're selling average products for average people. Not true if you have a niche.
It's not a judgment on the product. It's just a lament that the days of individuals or small companies innovating in the consumer electronics space are (long?) over.
I mentioned elsewhere in the thread, the best chance at making a wave as a consumer product concern is to make waves on some sub-component of the larger product being produced by the majors. You aren't going to compete with Apple, Sony or Bose directly, but you can improve on new technologies or extant processes and hope to get subsumed. That's the truly sad part.
