Past performance does not guarantee future returns. One could say something similar about the 50 year period ending in 1910. WWI, WWII, Hitler, Stalin, Mao and Pol Pot really skew the average.

If you look at the death toll in proportion to the population at that time, even that 50 year period will be less bloody than some others in the past.

Let me argue that the only reason for this is the atomic bomb and not 'technological progress' as a whole. Technology's 'ability to create' has virtually no bearing on any of this in my opinion.

To add to what Kitsune has said, the violence has simply changed into a series of proxy wars between nuclear powers, at the expense of non-nuclear powers. The other part is that for the first time in over a thousand years, Western Europe isn’t almost constantly killing itself in endless wars.

Still thanks to technology (e.g. radio, satellite, improved espionage capabilities).

Once again, thanks to technology. We're now able to do more for less, and many of the motivations for war (resources, land) are no longer as much as a contributing factor.

For values or “us” which are nuclear powers and their close allies. Of course if “thanks to technology” we end up destroying ourselves with nuclear weapons, climate change, or something as yet unforeseen then really what has come of it? Fixing nitrogen for fertilizer also led to the democratization of high explosives. Nuclear power and weapons are linked.

Look away from your personal circumstances for a minute and consider the trajectory overall, for everyone, and not just you. This Panglossian “optimism” is downright destructive. It feels a lot like being in an airplane which has entered an unpowered, uncontrolled descent, and the guy next to tells you to be happy, it’s a miracle that we’re flying, humans never flew in all of history until recently.
