This is perhaps a too extreme example and I wouldn't use ChatGPT for sorting a class list when it's trivial to do in a spreadsheet, especially because I'll probably need to have the list stored as a spreadsheet anyway to keep track of grades. However, from a more general point of view, there is value in having a universal interface that you can use to perform a huge variety of tasks, including also tasks for which it is clearly overkill. Using the right tool for the job means knowing what the right tool is, having it installed (or getting access to it), knowing how to use it, opening it and having one more window/tab to context-switch to and from, etc. Outsourcing tasks to an LLM that can be solved in traditional task-specific ways is extremely inefficient in various ways (cost, energy consumption, etc.) but it makes sense to save human time and effort... as long as it's for tasks that LLMs can actually do reliably, of course.
