On the other hand, a carpenter can buy a good hammer/set of chisels/block plane/circular saw - and use them for decades without cow orkers or project managers questioning their choice of tool and demanding they use completely different incompatible ones...
Imagine if every six months, your circular saw became incompatible with the version of wood you need to cut.
Meanwhile, the hammer you use is no longer supported, and breaks every time you pick it up, but using a new hammer means changing every single nail in the parts that you've already completed.
Then the job ends, and you look for a new job, they don't think you're qualified because you used the same chisel for two years, and don't think you'll know how to use the new chisel design that came out 3 months ago.
