I think this is because technological progress allows discourse between people living on opposite sides of the planet, aligning our morals planetwide, ditching what doesn't work in one society and adopting what they do somewhere else

it's good to share beliefs, opinions, and ways of living so that we are aware of what other options exist out there

I think this is what's going to end discrimination once and for all, because what we get to see isn't only what is filtered by public media like tv, which is often controlled by political agents who profit from racism and such

I wouldn't be so sure about that. We definitely got a lot of social progress from technology, but it's plain to see that social media gets massively abused for reactionary propaganda (not entirely unlike radio and print have been abused to further authoritarian ideologies in early 20th century). IME, in recent years people have been getting MORE cold and brutal, more willing to assault random people for being the wrong sexual orientation, they started assaulting EMTs, firefighters and train employees in significant numbers, and people have been outright murdered for telling them that they should wear a mask.

And every appliance becoming "smart" seems to further the corporate desire for planned obsolescence and making people unable to repair their belongings, along with massively increasing security risks and possibilities for mass surveillance.

IMO, we're moving backwards right now, with significant risk of losing the progress of the last 50 years.
