btw it's also about learning to crawl before learning to walk, before learning to run. THis stuff is tricky and there are many hidden problems; I rather start SIMPLE and understandably right, I don't want to go "full parallel" now (or maybe ever, no idea, we need to learn from this step first). Btw: I suspect the biggest gain comes from the first step or two.. after that you soon get diminishing returns...
