I replaced my 2019 Macbook Pro 13" i5 16gb/256gb, with an M4 Pro 48gb/1TB 16". It just wasn't worth it anymore, it would stall opening some large files, the fans would spin up for inexplicable reasons, the screen was mid... it was just barely serviceable for my needs and wasn't worth being so frugal about anymore. Yes technically I could use something from the 80s to write text files if I wanted to most of the time, and I'm somewhat anxious about the possibility that some component soldered to the MB will short one day and kill my SSD, but it's still quite a worthwhile upgrade.
