If I understand correctly, goroutines = asyncio (non-invasive) + asyncio.to_thread (when needed, but automatic). So, it is still cooperative concurrency that feels preemptive due to its design. This Go capability is interesting, and it 'seems' that it cannot be replicated without some integration with the runtime of the target language, i.e., a 'baked-in solution'. For now, I'm fine with true preemptive concurrency, but this might change in the future.
