It seems like kids and nerds are the first to discover new trends. See what kids are into now, and adults will catch on in a decade (e.g. Roblox in 2006, Minecraft in 2011) and just now adults are discovering the metaverse. Also nerds...I was using Zoom other video calling apps (e.g. Kik and Fring) for years before the rest of the world caught on in 2020. Bitcoin is a dozen years old and we still haven't found that killer app for crypto. Maybe 5 or 10 years from now grandparents will be using it. I had voice controlled home automation in 1999 with Homeseer and X10, 16 years before Alexa. It's getting more mainstream now, maybe in 20 years it will be the rule, not the exception. Paul Graham said it in one of his essays that you can imagine what the future will be like and then fill in the gaps with technology that will make it happen...picture most cars are electric and self driving 30 years from now. Most lights and appliances either think for themselves or have voice control. What will change between now and then to make that future possible? If most cars are going to be electric, most gas stations might convert to charging or hydrogen stations (can you build a business that facilitates that?). If cars drive themselves, what do they do when they are not driving people around? Maybe ownership isn't as important, and there will be more car (and other vehicle) sharing. If every light switch and appliance is smart and needs to communicate, what infrastructure needs to exist in every house? (Can you start a company that installs mesh networks or smart hubs in houses?). If crypto is a major way to pay, will there be more banks? Fewer? If more work becomes remote and some jobs disappear (e.g. drivers, cashiers, restaurant hosts/waiters), will people migrate away from cities? What will need to happen to support that?
