Almost universally, any time closer to today is better for most people in most ways than a previous time. But there are exceptions -- prehistoric hunter/gatherer lifestyle is superior in several ways to the modern one, but the risk of dying early in a horrible way is high enough that it's not true overall.
Should we live more like cavemen in very constrained specific ways? Probably. Do we want to force 8 billion people to starve to death by returning to that life? Heck no.
Similar, there are likely small parts of the 2000's that are better than today. That doesn't mean the 2000's are the peak of humanity.
