Humans have now about 20-30 year generations, so I think it's fair to judge our progress as a species in at least multiples of this.
I'm in my mid 30's and kids these days are way nicer to each other than they were when I was a kid. Bullying, making fun of kids of silly differences, etc is way down. I think the future long term, and in a two step forward one step back kind of way, is going to be better than it is now.
Human history is really bad on the whole, even the bad parts that exist today are often less mild or less common than what preceded our current era.
If you want to go back further, it’s estimated that 40-50% of adult fatalities in hunter gatherer societies were caused by murder, based off of historical evidence and study of modern hunter gatherer population.
There really aren’t that many eras you can point to that are really much better than the present for a typical human being. There are plenty of times that are better for the kind of person who writes history books, but that is a very different proposition.
Here’s a decent breakdown of the evidence for various state and non-state ancient societies[0]. Obviously there is some significant overlap between state and non-state societies, but in general the violent death rate in ancient societies is really high compared to even the 1800s, an era we consider violent by modern standards.

That study indicates that violence-based mortality is high in a few hunter-gatherer societies, but not in all of them, and also not in societies adjacent to these.
And you know what? It doesn't matter. The exact percentage of the population that got murdered is only one portion of the basic thesis that the present is the best time for the average human being to be alive ever. While the typical ancient adult may or may not have been murdered, the average ancient human would be dead before their 15th birthday due to disease (most common), malnutrition, or predation.
The worst countries today for infant mortality are in central Africa, with countries like Chad, Nigeria, and Somalia averaging a heart breaking ~11% mortality rate for those under the age of five. While I wouldn't run around shouting "this is fine and we should do nothing about it" compared to the entirety of human existence this is an astounding stat. There are royal families a few centuries ago that did worse than 11%.
No, these benefits are not evenly distributed. All in, you'd much rather be born in the US or the EU than in say, Chad. And quality of life does not improve linearly; you would much rather be a hunter gatherer than someone in an ancient Greek polis, where you were both more likely to be enslaved and where you'd probably live an even shorter and more disease ridden life. But if you had to pick any point in time to be a random, average person, now is the best time in all of human history to pick.
