> Parts of the GC language crowd in particular have come to hold some false optimistic beliefs about how well a GC can handle allocations.
Yep, the idea is "we've made allocations fast, so allocate away!". But that's a trap — every allocation puts pressure on the GC, no matter how fast you've made the very act of allocating. It's a terrible mindset to encourage the users of your language to have.
Then there's the more insidious problem — to make allocations fast you must have traded something off, like GC throughput. So now your GC is slower and encourages programmers to allocate, which makes it even slower.
