”If you're storing a reference on the heap somewhere, you suddenly have dynamic lifetimes with indeterminate reference counts, and it gets quite hard to 1) correctly manage memory and 2) verify that you're correctly managing memory.”
It is axiomatic that GC programs leak memory. I’ve never encountered one that didn’t. The difference is that it’s harder to see, and most programmers who have grown up with GC systems don’t know how to fix it.
”The alternative is that in all three instances in a GC language, I don't have to care about memory management.”
Again, no. The alternative is thar you aren’t paying attention, and don’t see the leaks until they become fatal. Just like cockroaches, you have them, somewhere.
”I have no idea how you've come to that conclusion.”
30 years of experience.
”For the vast majority of memory allocation in any GC'd language I can think of, you spend zero time thinking about memory management 98% of the time.”
No, you think about 98% of the code 0% of the time. The remaining 2% ends up causing so many problems that your amortized time spent on memory management is the same.
Having spent years writing code in both GC’ed and non-GC’ed languages, it’s pretty clear that it programmers spend about the same amount of time worrying about memory management with either paradigm.
The main differences are that people using GC systems spend their time doing magical incantations to manage the GC wizard, and they’re a lot more smug about the goodness of their system.
