I think that depends a lot on where you live and what you look like relative to those around you. I wouldn’t think black citizens in the US in the 1950s would agree with what you’re saying. An Asian coworker of mine said he always thought it would be interesting to go back in time and live for a little bit in the 1940s, but every time he thinks that he has to remind himself what they did to Asians in the 1940s here in the US.[0]
I do think that tech (particularly social media) has amplified a lot of the bad social behavior that people have always had. I don’t think there’s more of it, just that it’s gotten louder. Someone who could only be an asshole to the people around them can now go online and be an asshole to millions of people around the world at once.

This is not the right way to evaluate the benefits of science. This is the year those advancements start having an affect. The same thing was true about microchips the year they were invented, and about radioactivity, and even about the health benefits of washing hands and drinking clean water. All scientific discoveries are an investment in the future, and those four I just mentioned have at this point touched nearly every single person on the planet, just like the above list may well do in the future.
There isn’t strong evidence that the things you mentioned are actually going away, why do you believe it’s true? Women and minorities are getting more justice and fair treatment than they have in the past. People treating each other well is subjective, and it’s arguable how well they ever did in the past. But murder, violent crime, property crime and hate crime rates have all gone down for the past ~40 years. https://en.wikipedia.org/wiki/Crime_in_the_United_States Happiness is also subjective, but take a look at the Human Development Index and note how all 66 countries in the list on this page have a positive year-over-year growth rate. All of them. https://en.wikipedia.org/wiki/Human_Development_Index
eg: something like 99.95% of the planet (all but 1-2 Million) have 0 or near 0 benefit from most of those findings (save for maybe the vaccine). But important things are going away -- treating people well, having happy lives, justice and being treated fairly. It's not a good tradeoff IMO.
