When I say new technologies, I don't mean "new programming languages". Learning new libraries to make you better at your craft is part of "learning new technologies". Whatever the languages or the tools you use, you can always learn more and be better at them.
In my career, I've met all kind of programmers, and I'm sure you also have. Some are really passionate about their crafts while others do the minimum, go home and don't think about software until 9am the next morning. You are right that I can't say that good programmers enjoy learning new technologies. But I can assure you that the worst programmers I've worked with were never willing to learn more.
And, comparing software engineering with more mature fields is somewhat difficult as their tools do not change as fast as ours. Yes, craftman tend to know their tools inside-out; but they're not limited to only one. They're usually good with all of them and pick the right one for each situation.
