This has been a great discussion. Please keep it going. To the points on technical debt, may I also add re-validation? Let's say you have a weather model which your institute has been running for 20 years. If you decide to start again from fresh with code in a new language you are going to have to re-run known models and debate whether or not they fit within error bounds of the old model. That takes effort - which may of course be justified if you make gains in speed, flexibility or being able to use new hardware like GPUs.
