Do you believe that OOP should be phased out and we should start working on some alternative

Answer: No, working on alternative instead of OOP is not the best option. In this time of computer technology, there are many different ways to solve a problem. OOP is the choice of law when it comes to solve a problem using object oriented solutions. OOP is a way of developing software that sums up the responsibilities of the system in a company which works together on objects. Objects are not the differentiating characteristics of Object Oriented Programming, instead these are necessary for writing object oriented software.

Why we shouldn't use the other alternatives. Here are two statements which supports my opinion:

If a problem is classified or divided in many different categories, this will results in complex interactions, for which an object oriented modeling will be selected. The problems like these ends up in complex results in other models. The standardized approach towards solving problems is Object Oriented designs patterns. By using OO, solutions are generated, which are understandable for both creator and the coder. There are different numbers of design patterns of OO.
