One great opportunity is for expert-developers to push the boundary of better algorithms or libraries. No one rolls out their own cryptographic library, majority problems faced in our systems are common. If that common problem is solved once and packaged into a library to be used by anyone, no one else needs to bother looking at it. Most of modern software dev is all about plumbing. The harder parts need to solved once and that solution becomes available to everyone immediately.
