For background imagery in in-house presentations, I have switched almost entirely to genAI artwork. Previously, I would use a combination of licensed stock image services and small commissioned pieces on something like fiverr.

Now, I get faster turnaround and more choice/control in a self-service fashion. Do the resulting images hit the exact same highest possible high notes that a $20 or $50 piece of fiverr would? No, but they're usually 95+% as good and I get them in 2-3 minutes and can rev them as much as I care to.

I used to work in games; for game artwork, I suspect that creating custom in-house tooling may allow N/3 artists to do the same work as N artists could back in 2010. If it's even 3N/4, game studios will make that investment.
