Factual errors:

  • Interpreters neither need nor usually have a compilation step
  • Even processors are nowadays virtual machines, modern hardware only understands microcode AFAIK

Words which have a common understanding in the current compiler construction world, which you define in IMHO a non standard way

  • Compiler is commonly used to refer to tools which translate higher level languages (e.g. Java, C, Python, JavaScript) to a machine representation (e.g. JVM, Arm64, x86_64, MIPS...)
  • Even in academia Java is referred to as compiled/interpreted language (at the same time)

Factual errors about Java:

  • We have ahead of time compilers for a very long time now (GraalVM etc)
  • There are chips which implement the JVM in hardware

I originally had words about ahead of time compilers like GraalVM but got tired of looking at my own wall of text so I trimmed it down and left compiler to mean ahead of time compulers, which I see caused confusion, you're right on those points.

I know the JVM hardware exists also, but, it's specialty hardware even at the enterprise level. You could technically make an ASIC that executes QBASIC at hardware but I'm not sure I'd believe that makes it a compiled language since it would be neither wide spread nor the original use case for it. That's kind of a philosophical argument though

I think my use of compilers in interpretation may also be confusing, interpreters have an execution step, which at some point translates to a machine representation of your code. It's referred to as execution, but, it feels a lot like a compile+execute step
