I think about how technology changes our lives quite frequently. Its all about how technology is applied to solve a well defined and scoped problem. A solution without a problem (blind application of technology) is almost always a failure. I think image stabilization helps address a specific well defined problem that many photographers faced. This is what gave Canon a boost in marketshare in the 1995-ish... they delivered an applicable solution. Has it made people lazy? In general, I don't think so. However, I have seen some photographers with terrible stance. No excuse I can imagine except no one taught them properly or simply laziness.
From where I stand, the problem of shooting in low light was addressed mainly with the recent capabilities of digital sensors... more so than IS. IS isn't a perfect solution; subjects in motion, enlargements can still show a tiny bit of camera shake. In the film days, I lived with ISO 400. Sensors these days gives us high iso capabilities that is IMO more effective than relying on IS. It provides ample shutter and the ability to stop down a little from wide open. High ISO isn't a perfect solution either...
For me, I realized a while ago that technology hasn't changed photography all that much. What it has changed are people's attitudes towards it; Obsession with technology, Marginalization of skills/art form, anxiety over breech of privacy, etc..
I personally shoot primarily with a camera that doesn't have IS and still use a tripod when applicable. For portraiture, it helps keep the camera in a fixed position while I tend to my subjects. When I return, the framing is exactly how I left it. Its the same reason why I use one for landscape and some journalistic style photos.... it allows me to careful consider composition without constantly holding the camera in hand. I can take my time.... often leaving the camera positioned until I find the moment I am looking for.
One last thought..... I found on my camera (EpL1 and EM5) IS is less effective in continuous mode.
