Well,
After my six+ decades on this planet I have seen convenience increase massively. I have seen information explode. I have seen the population of my country nearly triple. I have seen food choice beyond my wildest dreams. I have seen international travel become so cheap and easy. Material goods beyond our wildest dreams in the 60's...
But
I have also seen the loss of the individual. I have seen the loss of privacy, even private thoughts. I see the roads crowded 24/7, tourist places choked and polluted. Loss of national identity as our country is awash with new permanent residents who seem determined not to integrate but keep their individual "community".. Simply too many humans generally... This of course leads to massive pressure on the natural environment.
But the greatest change I've seen is general mental health especially amongst young people. The volume of people medicated or medicating via soft and hard drugs/alcohol is staggering (in my observation). Suicide the silent killer on the rise. Self harming another hidden epidemic. It appears that people cannot adapt fast enough to the rapid changes in the material world but I cannot see the surge in tech slowing any time soon.
