Your data is showing that Scala grew from 0.01% to 0.03% over the past two years. Sounds impressive, right?
It's a relative number. Whenever somebody quotes growth numbers instead of absolute numbers, they are trying to hide something.
Let's take a look at the absolute numbers:

As you can see, Scala's line is a flatline around 0 compared to Java.
No, it is the data you asked us to look at and it refutes your claim that "they are as insignificant today as they were five years ago". They are _less_ insignificant. They may still be several orders of magnitude lower, but your claim is still incorrect.
The question is not about pick up (there is some, 0.01% to 0.03%, according to indeed.com) but whether that pick up is significant.
