I can tell everyone right now: a garbage collector has no place in the commercial industry as most of you might know. If there is no memory leak then there's going to be high CPU usage running in the background and the side effect will be a lagging user interface.
And perhaps more important, a sagging battery?
Is battery life not the more important reason to avoid garbage collection for portables?
And, electricity costs "at-scale". ;-)
And, most especially data center cooling costs. ;-)
And, the opportunity costs of lower processing throughput for increasingly
large data sets. ;-)
And, the less scalability for concurrent and parallel systems. ;-)
And, the shortened component lifespan due to increased loads. ;-)
And, the poor engineering design incentives they encourage. ;-)
And, the confusion/sloppiness and non-determinism present in the resulting
systems. ;-)
