Improving at...what exactly?

Please don't give some tripe about medecine or something...sure we have some fancy new techniques and the like, but that doesn't matter if those systems aren't generally available or rejected on pseudo-religious grounds.

It might be true we have been living longer for a while, but that's a trend of the past 50 years in some areas, not some inexorable progress towards longer lives...

Maybe we have lots of food and entertainment. I suppose that is good, in theory. But again, not something of recent history, that has more to do with the availability of large shipping vessels and TV production...

The part people may find optimistic is continuing to improve in any appreciable manner, versus some gains made decades ago...

Well, for one thing, neither me nor my son work in coal mines. We don’t have to breathe any of the sooty gases that coal burning spews forth, and can turn on airconditioning in summer when it’s hot. Also, heated toilet seats in winter.

Both of which are improvements not unique to even the past 10 years - even if you only recently experienced these improvements, that merely makes you "late adopters".

You can have personal improvement, and you can continue to reap the benefits of existing systems, this is not the same as general progress or, progress made by society, much less any sort of indication that progress will continue...
