Absolutely. New programming languages keep coming in. But what survives for long term are those which help solve business problems. Love them or hate them, but programming languages like Java, JavaScript, Kotlin, Swift do them more than any other languages for the Servers, front end and mobiles. Then there is Python ecosystem for the huge AI job market. Wearable devices take the challenge to next level along with all those advancements in mobile space. All these cool languages have a long way to go in building the eco system to be effective at these landscapes. By the time they try to get there, there will be new other languages that would be termed 'cool' at that point in time. And, the problem landscape will be elsewhere altogether. Then these cool languages would no longer be cool by then. Nor would they be addressing the growing landscape with their just growing eco system. they slowly fall into identity crisis and die down. I'm sorry, what a grim picture I'm portraying :-)
