I wonder why we need to learn Java?
Why should we write 5.000.000 lines of code for eCommerce, when we can set up nginx+opcache+jit and maybe some more..
Next we setup PHP 8, next we setup good MySQL indexes and 100kk records will "fly". Claude told me that if 100kk records "flies" - 100kkk records will "fly" too.
5.000.000 Java lines of code is equals to 500.000 lines of code wrote on PHP.
