Thanks a lot @jv22222 for sharing your own perspective apart from highlighting @genedangelo 's reply. Just to clarify, I am also not going through a crisis as such, thankfully. Just a doubt on future continued ability lingers on occasions. What you say, makes sense to me. After a few decades, we just see some patterns repeating with different names - RPC -> CORBA -> RMI -> Web servcies (based on SOAP) -> REST (based on JSON) -> Google RPC (going again to binary style) ... and so on. Not being cynical. Things progress in a way, but also have echos of the past.
