I'm also using a 2013 MacBook pro as my personal machine. I walked into the Apple store a few years ago with the intention of replacing it with a shiny new one. I hated the new keys and at the time couldn't get a physical ESC key, so I've been happily stuck in 2013 since. My employer gave me a 2020 MacBook pro (has physical ESC key) and it is a better laptop, worthy replacement.. But to keep personal development separate and save a few thousand dollars, my 2013 is still going strong.
