> absent of nuance Yes, this is a good point. It makes overly general claims. E.g. a GC proponent could claim "well, tracing collectors do no work for dead objects, so they have no overhead!" Which is a good point, but not the whole story. Tracing collectors may need to repeatedly traverse live objects. Sure. But then generational collectors only traverse modified live objects that point to new objects. True. And concurrent collectors can trace using spare CPU resources, incremental collectors can break marking work up into small pauses, on and on. There are zillions of engineering tradeoffs and the GC Handbook covers most of them really well.
