Are all the good ideas taken?

I've been considering ideas for a new software project. I have modest expectations, and I thought a few good ideas. But every time I research an idea, it seems someone is already way ahead in that area.

I've never seen so many new ideas on the ground at the same time. With the success of incubators in recent years there seems to be few green pastures left in the internet space. Does anybody else feel this way?
