This is more of the "Wendy's Chili" idea applied to software than any kind of investment mindset. For those unaware, Wendy's (a hamburger chain in the USA) has a policy that cooked hamburgers need to be served within a few minutes of being prepared. This keeps the quality of the burgers up, however, it also causes a lot of waste since burgers need to be prepared ahead of time to really be "fast" food. So the founder of Wendy's decided to refrigerate the unused patties and use them the next day to make chili. Chili wasn't a high margin item, it didn't make sense to make it from fresh hamburger. It was really a way for the company to offset the costs associated with serving hot, fresh burgers. Finding a way to leverage code you've already built but wasted is a great idea. But that's not necessarily a great idea to go about intentionally wasting time in the hopes that you might recoup something back later. Keep focused on making high quality software first and foremost, but if you have some scraps left over from that focus, definitely find a way to make chili from it. Just don't get into the chili business.
