You don’t have to be an expert in everything. BUT I firmly believe that you should be aware of most things.

You don’t have to be a data scientist – but you can understand a bit how data analytics work. You don’t have to know the ins and outs of machine learning – but you should know how to talk to AI to get the results you want.

For example, I’m taking a Python course now with freeCodeCamp.
Is it directly related to my field? Heck, no.
Will I be an engineer for Google next year? Highly unlikely. (Though, Google if you have any advice on how to be in the running, let me know.)

BUT…
Is it helping me understand how coding works and some basic programming? Yes.
Will I be able to recognise certain parameters if someone puts a screen of code in front of me? Sure – not everything, but I can get the gist of it.

So if you don’t want to be an expert, be a amateur.
If you don’t want to be an amateur, be knowledgeable.

Can’t hurt.
