I'm debating whether to keep the MBP 13 from 2016 with 16 GB RAM and 256 GB SSD or buy a new base MBP with quad core CPU and with the same amount of ram and storage. I would sell my current MBP so that the cost would only be around $ 400.
I use it mainly in school which consists of writing essays and a lot of programming in the form of React web programming. I'm also going to start learning computer science in the form of ML and stuff now and use it a lot for it in the coming years, which is why I even discuss whether I need the upgrade to begin with.  What do you think?
Thanks in advance!
