Here you attempt to distract from the basic dishonesty of your inter-generational "whataboutism" through critique of something GP didn't suggest. GP's observations of the present and near-future are discouraging, but they're accurate. The cavemen and the serfs are not our opponents; our opponents are alive right now. GP speculated that we could be kinder to the dying (seriously, that's what you're arguing against), but didn't recommend surrender.

[I had a suggestion for "action" here, but I deleted it before posting.]
