The tradeoff space you’re describing doesn’t reflect reality. Adding more brackets and pointless keywords to a language doesn’t meaningfully improve the programmer experience in any way. There are plenty of terse languages that don’t require an IDE to understand. If anything, Java effectively requires an IDE to use because it’s so verbose.

The things that I write in a computer program’s code should correspond as closely as possible to what the program means - nothing more and nothing less. Java is terrible at this.
