The point you're missing is that it's about the future. I generally agree, but it's obvious everything becomes more RAM intensive as time goes on. Hell, even games can take more than 8 GB of purely VRam these days.
It's really not weird. The more you charge for the base product and upgrades, serving the bare minimum becomes less acceptable. It also doesn't help that the 4GB base models from years past aged super quickly compared to it's higher end cousins.
As devs and power users we'll always have an edge case for higher RAM usage, but the average consumer is going to be perfectly fine with 8GB of RAM.
All of these comments about how 8GB of RAM is going to make it "unusable" or a "waste of components" are absurd.
