It's hard to read this as anything other than a bitter candidate who got rejected after a series of FAANG interviews. There are some legitimate criticisms sprinkled in, but to characterize everyone who made it through as slaves who are more obedient than you seems like a coping mechanism.
This looks really cool, can't wait to check it out. The problem I've seen with other tools I've tinkered with is that they do well with simple stuff like:
"what are my latest orders" -> select * from orders where user_id=x order by created_date
But really struggle when you have a complex schema that requires joins, and basically has no support when you are describing something that needs outer joins or the like. Would be great to hear if DataHerald has cracked that nut or if it's still a challenge for you as well (no judgement if it is, it seems like a hard problem).
