Gotta love JSON. It's XML without the tools so you get to reinvent everything to pad your resume. XML -> JSON WSDL -> JSON schema XPath -> JSON path XSLT -> JSON template? SOAP -> Swagger and friends One or two decades from now there will be too many tools and things to learn about JSON so another generation will reinvent a new "perfect format for everything". And a new cycle will have started.
Too many tools? Are you not selective about what tools you use anyways? The field is decades old. Do you program in assembly? Fortran?
