Typewriter text effect usability

I've been asked to implement, and have seen this typewriter effect on a number of web sites: https://mattboldt.com/demos/typed-js/

Typically it is in the header with 3 or 4 sentences about what the company or service does. I'm not sold on the idea, while it might be a "cool" effect, will users hang about waiting for the sentences to load or skim and scroll past it? Or am I just being a kill joy?

Just looking for some expert opinions on this technique and if it is an OK or bad experience.
