Wheres Java?

Generally learn anything thats proper lamguage and as new as possible. Newer languages are often (not always) better as they learnt from mistakes in the past. Some say language xy will still be supported for decades bcs it would be used in a lot of legacy. I dont think thats correct: in last 30 years most languages appeared, in next 30 we will make exponentially fastee progres, lamguages will come fast and some disappear as fast. I think Rust and C# have still some good future ahead.
