Good people are indeed dying now, which begs the question of why we would double down on it with accelerationism in the hope that the remaining humans have a change of heart somewhere along the way. That's the stuff of movie plot lines, not reality.
Some form of radical change is necessary, definitely. But doing more of the current system isn't going to lead to better outcomes. It leads to the same outcome, just faster.
What else do we have? There have been multiple revolutions and regime changes in human history of varying success and violence. We could learn from some of those what makes a revolution more helpful or harmful and attempt to replicate that. It's worth a shot before we just accept the sacrifice of society's most vulnerable in the hopes it somehow increases empathy among those who were always fine with those people suffering.
