We do sort of use the internet as a crutch, but that's all technology. All technology was invented as useful crutches to make life easier.
As for the internet alienating us... that's somewhat true. No doubt I would interact with actual people I meet in real life if I didn't have the internet. But you know what? All technology has its downsides. Everything, in fact, has a downside if you think about it long enough. But that doesn't mean it's bad.
The internet has its flaws and does create some problems. But so does everything else. We can't point to the flaws and say "It's not worth it!" because if we did that we'd never get anything done at all.
