It IS necessary, just not for you. Everything you're saying has literally nothing to do with this topic. Please stop with the desktop replacement nonsense. There are already phones with this much RAM. And I know Android is less optimized than iOS, but there isn't enough optimization in the world that will fix running out of RAM. It's great you aren't ever in any situation where you need this much RAM, but you don't represent everyone ... clearly. This topic wouldn't exist if everyone was like you. Apps refreshing because RAM ran out is, in fact, a problem.
Nobody is trying to replace their computer with an iPhone. That again has literally nothing to do with the topic. We're talking about the phone, all by itself, in certain intensive applications, requiring more RAM. It's a thing or this topic wouldn't exist. So please just stop.
The only one inferring that is you. What you're doing is straw manning and it's very unhelpful. This is weird hill to die on. Again, what you do with your phone doesn't represent everyone. Hop outside of your bubble.
