There's an evolutionary process at work, so it's not really about that rewrite decision, it arguably made sense fifteen years ago to pick C++ - yeah C++ will still exist in say 2040 just like COBOL still exists today and I don't trust anybody arguing otherwise. But whether investing in C++ still makes sense is a different question. That might influence career decisions, and what new projects should do even though a choice fifteen years ago was correct, and it also impacts how to manage your existing project. We do these night walks out in the Forest. 2-4 hours in the countryside, when it's still pleasantly warm but no sun. Owls, bats, insects and occasionally horses or deer that were not expecting humans - no sudden moves because horses or deer can easily kill you by mistake if startled. Without much light it's hard to be sure whether you're on a trail and if you've reached the fork you expected or just a place where there's a tree in the way. So, it's not rare to realise we've made a mistake. Now, if you realise after 5 minutes you can "just" backtrack. It's nowhere near as easy in darkness, but it's possible and arguably preferable. However it is also possible to realise after say an hour. You thought you'd be in a clearing, on a ridge, but you're a mile away approaching a river crossing. Oops. It is usually not correct to retrace your steps in this case, you need a new plan taking into account what you know now about your position.
