The reality is: yes, that could be. I believe more that they may have later 50/50. And that is good as it is., Cause Java is in a high amount of business applications the main language it is simple logic that Java needs to implement AI in a high grade. As Azul and also Oracle say they are working on further implementation you can see that java will come up with it. I have no doubt that the language has the capabilities and also no doubt that it can handle the threads needed for AI. But, like always: there is an existing structure which will not change from one minute to another to Java. While Python is also a reliable and performant language and it is working good together with Java many devs will decide still to use Python for the AI part.
In all projects which are mission critical and have to be extremely secured like in finance or also defense and Aircraft we Weill see the different: there people will implement Java instead of Python. For me this is not the all deciding race.
