Quite the opposite - the developers of many platforms, say social networks to take an example, have a lot to answer for in the way their "useful projects" have actually had large negative side effects. I think you're really reaching if you think that someone not spending all of their time on directly productive pursuits that affect the lives of others materially is somehow a problem. I'd honestly be hard pressed to come up with an idea for a technology I could create tomorrow that would have a real positive impact on humanity (as seperate from say, slightly improving some obscure programming tool). Those problems are political.
