> but after 10+ years they still just work I think this is also a mindset of devs who are committed to a job long term. Many places seem to churn through people every few years. If I had to look for a job every year or two I'd be doing resume-trendy "best tool for the job" stuff too. If I knew I'd be on the same system in 2029, I'd be keeping things easy to maintain.
And in all fairness, many people seem to churn through places every year or two because (among other reasons) they value newness over longer term projects.
That last sentence really should be, "You’re handing developers a ball of chain and padlocks and telling them to feel free to bind you to the operational toil that will be with you until the sweet release of grim death." They can (and will) pack up their tents and move on well before any consequences appear.
