In some areas its doing some very exciting work, if you believe in yourself enough you might think that you can shape the future of AR or VR. (if you're a software engineer, then you'll be one of 4k other who are doing that)

For a hardware engineer, you are going to be given much more free reign, and don't have to worry about the cloak and dagger cult shit that apple insist on.

also, a stonking wage.
