I’m not questioning the value of Scala. However, it is absolutely clear that after 15 years, Scala still hasn’t broken into the Top 10 languages. That was my only point, so where is the ignorance?
Fact: Scala is #26 at TIOBE, #18 at IEEE Spectrum, #16 at PYPL, and #13 at RedMonk. At StackOverflow Develop Survey 2019, Scala has a measly 3.8% of the votes for “Most Popular Technologies.” Even Kotlin has 6.4% and Java has 41.1%.
At Githut.info, Scala is #19 for most active repositories. Java is #2, Golang is #14, and C# is #10.
Scala is definitely a major language. I am not disputing that. However, I see no evidence that it will ever ascend into the Top 10. I see no evidence that it will ever come close to displacing Java. Scala is, at best, a second-tier language.
