Wow, some minor complaints on language formality issues, then discredit the thing as a whole.

But in the end, the author probably does not understand PB solves the inter-language data sharing problem, which makes all its complain secondary and inconsequential.

It's like complaining a car that drives fast and has great gas efficiency of cannot talk. (Well in 2018, it might be less of a stretch to demand a car that can talk)
