I don’t find this piece compelling. Go does offer performance benefits. However, most web applications do not reach a state of maturity that justifies a rewrite. The acknowledged initial development time advantage Ruby offers is compounded into successive development cycles. SOA is not necessarily a good architecture objective, and API structure arguably benefits more from Rails’ defaults than Go’s constrained syntax. Finally, more Rails developers interested in improved concurrency programming would adopt Phoenix than would adopt Go.
