> "You can also bet that a full stack js dev would rather buy your Kafka wrapper than learn Scala, which will do nothing for her career prospects." My reading comprehension is bad then because that's a very confusing sentence. - There are lots of full stack devs that would rather learn scala than a kafka wrapper. In fact, I would say it's more likely because a full-stack dev is inclined to be more flexible and learn different tools. - Not really sure that kafka and scala are one-to-one comparisons - I am also not sure which one "which will do nothing for her career prospects" refers to. Is learning a wrapper for kafka useless, or is learning scala useless in that quote?
