I'm directing my criticism specifically on the technological advancement which is devoid of communal spirit, not on all technological advancement categorically.

Crediting human achievement to technological advancement is a mistake in my opinion. Technological advancement is not inherently good or bad. Communal spirit is what determines whether technology yields positive or negative outcomes. That's the real ingredient behind everything humans have achieved throughout history.

Sadly techno-optimism has become a prevailing mindset in today's world where people and institutions don't want to take responsibility for the consequences of their actions because of belief that as-yet-unknown technological advancement will bail us out in the future, even when there's no evidence that it will even be physically possible.

But what I said is that your view is a sad one, not an incorrect one. The truth is, technological advancement may truly end up being the defining characteristic of humanity. After all, when we think about extinct species, we tend to associate them most strongly with what made them extinct. Just as we associate the dinosaurs most strongly with a meteor, maybe an outside observer will some day associate humanity most strongly with the technology that sent us out in a blaze of glory.
