True but we're not done building game engines. It's not a solved problem. New hardware, new problems. New code. The point of the Handmade Hero series is to show people how every system is done. It exists because almost all literature and media on how to make games is presented from such a high level that there aren't enough people in this world who know how sound works or how the graphics pipeline works from a holistic perspective. It's all too much a black box and we're told to program with these high-level abstractions without understanding how it all works. This series is for people who literally want to see what's involved in building a system from nothing. It's not necessarily about designing and making a game. It's about building game engines. Presumably it will give the next generation of programmers a foundation on which to build the next UE, Unity, etc.
