Chinese wheelbarrow optimized for different operations than European one. First, you have to lift load higher for Chinese wheelbarrow. Second, you have to be more careful with Chinese one, because overloading of wrong end will dump all load to ground. Probably, one man loads it while another man carries. It looks like Chinese wheelbarrow is optimized for one scenario (separate loader and operator) and European one for another (same loader and operator). Also, you can drag European wheelbarrow instead of pushing it. This way you get rid of many difficulties in operation. We did that when I was young and had less power and worked in gardens and/or construction. To conclude, author does not distinguish between different use cases for seemingly same instrument (e.g. BerkeleyDB and SQLite) and he does not apply enough reasoning against his own argument, just to be fair. What many consider NIH is often deliberately optimized choice for some specific and important use case.
