You know, I thought the same thing back in early 1997. We could almost deliver (analog 480i) broadcast quality on a CD-ROM! What was there left to do? I was actively planning my career pivot to film restoration.

Then Peter Jacobsen called up and asked if we can use this new RealVideo beta thing to embed some golf clips into his web site without buffering.

xHE-AAC is a big material improvement for important markets. We could have 10x the efficiency of HEVC today and deliver pristine UHD HDR over 4G networks.

Or deliver a great full-screen experience over a 2G network to people riding a bus in rural India. 720p @ 20 Kbps would still be a worthwhile improvement over 720p @ 30 Kbps.

I am confident that incremental improvements in compression efficiency will remain a multi-billion dollar market through my retirement. The main thing that could cause things to slow down is if we really hit a wall in terms of silicon process nodes, and stop getting big year-on-year MIPS per watt gains. If we were stuck on the same node, we might start running out of exciting new things to do after a decade or so.

There is still a huge market for improved MPEG-2 encoders...
