Modern languages abstract a lot of manual tasks, not automate them, which can lead to issues when developers are unaware of underlying processes.
In C, memory allocation error handling and limits are explicit, unlike in Python where such details are abstracted, potentially leading to unexpected crashes.
Dynamic behaviors, including dynamic memory allocation, require detailed understanding and optimization, which can be hindered by languages that hide complexities.
Type-annotated and dynamically typed languages may provide convenience for developers but may not directly impact code performance unless optimizations are explicitly made.
