Data Engineering
My belief is that data utilization is still low. Many good tools for using data and extracting value from it exist. Fancy pipelines, automation and lately intelligent systems can be built on top of it.
Personally, I have found myself in the other end of the “pipeline”, i.e. collecting it. The tools there are underdeveloped and maybe they don’t even exist yet. The processes vary, but are often not standardized or disciplined enough to provide much value.
This is an area I personally enjoy exploring. My professional work also revolves largely around it. It will be interesting to follow the development in this area in the coming decade or two!
