We all know that Facebook controls React and Google controls Angular and so on., similarly Salesforce will control LWC

Moving away from Oracle DB is a herculean effort given the heart of Salesforce is still a lot of PL/SQL code :) To be truly scalable in the modern sense, they should move to a reactive architecture - which means they would have to completely rearchitect the platform with a non-blocking backend. Unfortunately, there aren't many options for them as JDBC can't do non-blocking IO.
