I hear ya. If you feel you've lost your perspicacity, fear not; it's always in the last place you look. But... yeah. A colleague (25+ years) has to deal with this more than I do, but have hit it some over the years, and it happens more the older I get. Often he or I may be 'right' but only because of existing constraints in a system. Someone with a different view may even be 'correct' in a nuts-and-bolts technical sense. Yes, A is 8% faster than B. But... we have an existing system in B that meets our current needs, and team who know B, have written it, and maintained it for a couple years. Switching tech stacks to something no one knows for an 8% network speed boost is not remotely helpful.
