> Analogously, reimplementing adds value because you learn to make something better or faster or simpler. And you learn how to make it and can now take that knowledge elsewhere and use it in unanticipated ways. You know, there’s some truth in this. At the same time, there is only truth to the extent that the person reimplementing is actually striving to do better. I would bet that well over 99% of reimplementations are strictly worse than the thing they are mimicking. I spent a bunch of time implementing a custom windows framework similar to WTL. It was a great learning experience. I would also say that in no way woks it have been useful to anyone for or to appear in an actual product. In most ways it was doubtless inferior to WTL. I used it for toy projects and that’s what it was.
