My 2013 MacBook Air screen recently died. I just bought a new one off eBay from the same year. Teenage me would not understand. But I think personal computers peaked years ago. The reason this is possible is I have opted out of “modern” development tools and I write all my own code with a minimum of dependencies. If I was using webpack and Docker I would have to buy a 2018 machine.
