Earlier quoted context omitted.
A lot of modern websites even add an intentional delay for buttons to respond or even load because it "looks nice."
Unsure what exactly counts as "looks nice" but I'll often add an intentional delay to buttons whose actions are near instantaneous but not great to do multiple times so that you don't accidentally click it twice.
I'm thinking something way less necessary. One example off the top of my head is https://www.apple.com/iphone/ with all the text appearing slowly as you scroll down. It's kinda understandable cause it's just the marketing page. But some websites have these slow animations everywhere, both for elements appearing and for button clicks.
