The consumer electronics industry is desperate for something new they can sell to everybody. VR headgear was the last big hope. There's nothing after that nearing production. The industry is forced into price competition on existing stuff. Look how cheap huge-screen TVs have become.

This is the downside of the "digital convergence" - no need for new hardware; new things are just apps.

Some of the next big things turned out to be too hard. Flying cars - batteries still too heavy, jet engines still too expensive. Self-driving - harder to do than expected, hardware too expensive. Internet of Things - to do much of anything that affects the real world, it requires installation, which Silicon Valley isn't set up to do. (If "we service what we sell" Sears was still around...) That's also the big problem with home solar. Robot vacuum cleaners - still not very good vacuums. Robots that can handle things - robotic manipulation in unstructured situations still works badly after 50 years.
