Different tools in different years as expectations have changed. The TI-89 is incredibly powerful, but has to give way to MATLAB and Wolfram Alpha. It used to be productive to “google” your problems. Going further, there’s now LLMs writing python code to do calculations. Hard to say what’s next, but I’m sure what is considered ethically questionable today will be acceptable and the new thing will be the new questionable tool.
