I'm sorry, but I don't understand the question. Is the purpose of using screensaver different in 2018?
Purpose of screensavers was to save CRT monitors from screen burn-in.
Now is 2019 and LCD panels. So, main purpose of savers is obsolete ;)
Well I use screensavers so that my MacBook look more cooler. And these screensavers definitely accomplish that purpose. 😁
