In retrospect I think I was thinking of PFAS. I’m not sure if that’s technically a microplastic or not. Anyway; I would imagine intaking chemicals that your body is unable to remove effectively is probably bad no matter what it is. As bad as mercury or lead ? Probably not. I guess the question to find out is what thresholds of microplastic content correlate to how much negative health outcomes.
And yeah, the irony of the same corpos that poisoned the worlds water supply with microplastics wanting to sell you a microplastic filter wrapped in plastic container isn’t lost on me and most definitely will happen.
ARC can memory leak if you don’t properly use weak references when appropriate. You trade GC ticks for having to deal with a counter. generally GC will (raw language performance aside) have higher throughput (because its not spending time doing ref counts) but will have more sporadic latency because if the GC ticks, then your program is basically on pause until it’s done.
Comparing them as if one is better than the other feels like painfully missing the point. Completely different memory models. And if you’re only slightly making use of ARC, then switching to a GC is a big jump.
