This you can apply to almost everything we have been doing in the last 50 years I guess.
We're constantly being told to buy new because 1) more energy efficient, 2) better in terms of safety, 3) more environmental friendly, 4) it was built with unhealthy materials, 5) a single component is harder to replace later it with more modern xyz, if you don't replace the entire system the component is part of, 6) costs are increasing, so do it now!
You just need to understand which of the items above is essential for you, impossible to say no to.
