Although I agree with most of what the author says here about scala and its benefits and features, this is hardly a debunking and more of a strongly opinionated defense. Some of the arguments are along the lines of &quot;hey SBT isn&#x27;t just a bunch of symbols&quot; or &quot;I upgraded my MacBook and compilation times are not a problem&quot; or &quot;tooling is better now&quot;. Reassurances yes, debunking hardly.<p>Scala compilation time is probably the worst problem I have with scala, and it still is frankly. I have seen no evidence that this has improved from personal experience and after talking with devs I know working in large scala code bases (Foursquare, Twitter).<p>Even if there are speed improvements in the scala compiler in future versions, the author doesn&#x27;t address binary incompatibility between major scala versions either which, along with slow compilation times, makes it a serious PITA to upgrade to a scala version that might actually compiler faster.<p>[edit] hit submit too early last time, re-edited after regathering my thoughts.
