I agree! “Pro” is just a marketing term which means slightly better than the base model. It has nothing to do with whether the machine is used for professional purposes or not. The whole argument about what kind of computer has “professional capabilities” is fallacious; if you are using your computer for work, then you are using it professionally and the kind of work you do will determine the kind of computer that you need.
There are many highly regarded professions do not require high performance computers, e.g. doctors, lawyers, writers, accountants, and any other any number of jobs that just require a machine for communication and information access. Even technical jobs don’t always require high spec machines. For example, I was able to manage the cloud infrastructure of several large enterprises with nothing more than an 8 GB MacBook Pro, but I could’ve done it with a Chrome Book or a relatively low spec Windows machine. This is professional work which earns me a good salary. Similarly, when I want to edit my travel videos, for which I am not paid, I need a much more powerful machine. This is not professional work, yet I need the so called “pro machine” to do it, or at least I used to before the Apple Silicon Macs.
In short, you need a machine that is suitable for the task in hand, whether it earns money or not. Perhaps Apple should have just called these machines ”Plus” instead of ”Pro”
