8GB of RAM is about $50 right now. If you have to replace that every $2 years, are you really complaining about the cost of $25 per year on your $1,000 computer system? It's a rounding error.
Chrome, in particular, is generally be used for far more tabs (I have like 30 open right now on a MacBook Air) and increasingly complex web sites every year. It's easy to look at memory usage and complain, but the fact is that our usage and the size of the pages we're loading is also rising rapidly. If you loaded Chrome from two years ago and used it how you work today, you might not find the memory footprint that much better than the current version.
