> I have a Python program I run every day, it takes 1.5 seconds. I spent six hours re-writing it in rust, now it takes 0.06 seconds. That efficiency improvement means I'll make my time back in 41 years, 24 days :-)
The key here is "I run every day" - if you're only saving CPU for yourself once a day then, well, fine. But if the improvement is about something that runs millions of times a day, or is run once a day by a million people, then that's something completely different!
