Heck, almost nobody even had a remote control back then and a 27" console TV was considered huge [screen wise]!
Yet, that very TV exists now... made by Samsung.
There were no physics laws preventing people from making such TV 30 years ago, the technology simply was not there. What we are talking about here is different, there is a physics problem that we can't work around. It's akin to exceeding the speed of light; can't be done with our current understanding of the laws of physics. Any medium transition will cause some light to bounce back and this will distort the image. Sorry if I burst some people's bubble.
