Hey, do what works for you, kid. (I say that respectfully). If you're passionate about writing a neural network in Fortran...

...then do it. If you follow one of the practical solutions here and it makes you miserable, then don't do that. There are easier ways than Fortran, but if you accept that it's not necessarily the most efficient or easy, like, at all, way to go about things, and this is a passion project for fun, then that's something you can learn with. Whatever fills your sails and gets you _learning things_.

I think you want to ask yourself why Fortran specifically (it's a low level language, you like it in particular, older supercomputing history, etc?)

Once you have written down all of the _why_ for what you want to do, make sure that you've chosen the right building blocks (the _what_) for it.

I hope this helps you on your journey. Much love and care from this fair enby over here! <3 <3 <3 :DDDD
