I think his point was that loading up the memory and space on your smartphone is rapidly becoming a non-issue. I haven’t had a 16 GB smartphone in almost two years. My current one is 128 GB, and my wife has a 64 GB iPhone. Plus, I have an old 16 GB iPad, and iOS has been able to offload apps without deleting my data since at least iOS 11, which came out last year. So, I don’t have to worry about space much at all anymore. The iPhones can store everything I could possibly want, and the iPad rarely needs my intervention and can decide on its own which app(s) to offload anytime I download something new.
