You're missing the point, for realtime rendering it's not enough for the content creators to have this technology to get the benefits, it has to be used on the target end user hardware too. Getting things to look good with traditional rasterization based pipelines involves a lot of special case hacks and tricks and work arounds for situations where they break down or don't compose. That is a lot of work for the artists to accommodate the limitations of the target platform. The promise of raytracing is that you can get great results without a lot of tricks and special casing which frees up the content creators to focus on the visuals they want to create without worrying so much about technical implementation details. That only really works if the target platform supports performant ray tracing as well as the content creation tools.
