What were you expecting? Each program is actually a VNC client that connects to a server that has super secret Valve room temperature quantum computing hardware and a NIC based on laser cutting OCRable messages onto live crabs?
I'm occasionally frustrated that I don't know how to do lots of things in Photoshop and Illustrator, for example, but don't have enough incentive to learn how to do them. While I don't think achievements would work for me, there are undoubtedly many people in a similar situation for many kinds of software that it would work for.
