What do the wealthy have now that will roll down to the rest of in the next 10 years?

I was car shopping this weekend and was blown away by the tech features that are available in even moderately priced cars. Adaptive cruise with lane assist, blind spot monitoring, backup cameras, navigation and even reverse automatic breaking. Even base models had quiet smooth rides.

When I bought my last new car 10 years ago, this was only the stuff of luxury brands. So that got me to thinking, what luxury commodities will become affordable in the next 10 years?
