For instance, transportation is a "human problem". It's being successfully solved with such technologies as cars, trains, planes, etc. Growing food at scale is a "human problem" that's being successfully solved by automation. Computing... stuff could be a "human problem" too. It's being successfully solved by computers. If "human problems" are more psychological, then again, you can use the Internet to keep in touch with people, so again technology trying to solve a human problem.
