You could argue that’s a definition of success for a gadget: when it is ubiquitous and necessary.
Time to get in on some new gadget that will soon be a boring ordinary part of life. Electric Vehicles look like they will but still pretty expensive. My vote is home automation stuff
Most charging happens at home. There are still some hurdles, but lack of charging stations is not the argument against mass adoption of EVs that you think it is.
Sadly I can't find any hard numbers but this report states "The project shed light on other facets of PEV use. It found that public and workplace charging infrastructure enabled drivers to increase their electric driving range, although most drivers did not charge away from home frequently"
edit: nevermind, there is another report that states "According to the U.S. Department of Energy, 80 percent of EV charging happens at home"
I have VR and I don't see how that would ever reach mass adoption. I think it will forever be a toy for people interested in techy stuff, and only be a tool for very specific jobs.
It's just not really useful in any meaningful way to most people. Why would I replace a regular monitor with VR if all I do is organize spreadsheets and write emails?
