It's "lazy" in the sense that you look for the simplest most leveraged way of doing something well, not "lazy" as in negligent. A lazy programmer takes time to search for the things that the OS will do "for free". Keeping up with and using, the latest developments in OS libraries. This can save you a lot of coding, and gives you capabilities that are likely to keep working on diverse future hardware. A lazy programmer will check in the smallest possible fix when fixing other's code. The simplest change takes time to isolate, but it causes the least disturbance and reduces chance of side-effects and new bugs. It also makes the change comprehensible to others, which saves time having to explain it. If you do something right the first time, you don't have to do it again, and in order to do that you have to do it simply and carefully or you will never get it right.
