I don't know what I'd do if I had to go back to writing down a grocery list and keeping up with that list. For years and years I have been using my phone to keep my grocery list as well as other lists. About 7 years ago I made that process even easier by adding Google Home/Nest devices to my house. No matter where I am in my house, I just say, "hey Google add milk to my shopping list"... there is a Google device in every room so I don't have to go to the kitchen to talk to Google. When I'm ready to make an order, I use a split screen to open my shopping list and Walmart and place my order online.
As far as learning a new phone, I'm tech savvy so it's not a problem. If I need help with new features I'll Google it or search YouTube for a video. I bought my second Smartwatch last October. First new one I had in 6 years. Probably still don't know half of what it can do but if I need to know something it's a lot easier to Google it or watch YouTube than it is to look through the online manual. Speaking of online manuals, if you use those, a little tip is to do a search for a keyword in your query rather than browsing the chapters.
I average a new cell phone about every 4 years. If you have Alexa or Google, and you tend to misplace your phone regularly like I do, you can ask either one of those AIs, " where's my phone?" or "find my phone". Even if the ringer is off, it will ring your phone. My new robot vacuum will also be able to take voice commands through Google. Google can also do what's called continued conversation. You have to enable it . So instead of saying Hey Google with each new command, if you continue to make commands within an eight second time frame, you don't have to say "hey Google".
