The practicality is a very personal thing. For me, it's helped me see that a wider variety of things match the definition. Realizing an Actor model, communicating processes, microservices or nodes in a storage model can all be seen as objects, and applying some object oriented modelling techniques to them, has been a very powerful tool for understanding them and building them. This value is entirely personal to me, though.

No apologies necessary, it was absolutely fair to call me out on a bias on my end. You too thanks for the discussion :)
