Yes, it has made man lazy. There are a lot of shortcuts that we've created for ourselves using technology. Some of these things are not that bad, and have allowed us to further advance other avenues of industry, but others are really just to make our lives easier. Cars for example, that is the best example of technology making man lazy. People tend to drive even when they don't need to. Hopping in your car to drive the couple of blocks to school or work really is not necessary, use a bike or even just walk. It'll make you healthier in the end and will save you money!
Technology can be a wonderful thing for our society, but it definitely has made it a lot easier to be lazy.
