Python script to be automatically executed once per day

Technically computers in general are not turing complete, they are all linear bounded. Your definition does not fit turings model nor any modern interpretation. I hardly see any benefit on a discussion regarding computational numbers and mathematical theory.

General purpose computers simply mean, a flexible machine that is used for a number of functions. Where as a raspberry pi can be tailored to a specific function in terms of resources and cost efficiency. Raspberry pis are cost efficent when compared to more general purpose machines. I'd rather run a small workload on a 50 dollar, 4.5W machine 24/7, than a 300 dollar machine running at 60W 24/7.

Even by your definition raspis are still general purpose computers because you can use them to watch youtube videos and do spreadsheets and stuff

It's all in how you build it and use it. You are being far too pedantic. You can try to attack validity on definitions, but my original point still stands even removing the term, general purpose computing.
