Maybe they would become sort of invisible words, like said, if people used them consistently, .
I don't expect this to happen. And really, it would be a loss to the language if it did. 'Laughed' is a fine old word.
In the meantime ... the basic problem with, 'he grinned' and all its cousins, is that they are commonplace, overused dialog tags.
Lookit the dialog tags here.
"She's selling cherries," Peter opined.
"Just what kind of cherry is that?" Mark grinned.
James laughed. "Exactly the kind you think."
"Har Har," Peter sneered sarcastically. "Big joke."
"I didn't say anything," Mark averred. "I was just thinking--"
"Will everybody just shut up," Mabel scolded.
'Saidisms' and 'laughisms' make dreadful dialog tags. Often, they're used without precision.
Other categories of overused dialog tags are
'lookisms', (she watched, he noticed, they saw,)
'facial tics', (he raised an eyebrow, she grimaced, he snorted,)
and 'body twitches', (he turned, she sat down, he shrugged.)
Yes, use them. They aren't evil words. Just use them judiciously.
It is often better to tag dialog with action, internals, or large body movement.
Tag with 'story'.
"She's selling cherries." Peter hacked at the hole in the ice
"Just what kind of cherry is that?" Mark hunkered down next to him, shoulders shaking, amused as hell.
"Exactly the kind you think." James was clumsy with hilarity. He almost dropped the ice axe.
"Har Har." Peter wasn't in any humor for this. Iimpatiently, he took charge of the axe before James hurt himself. "Big joke."
Mark hunched together tighter. "I didn't say anything. I was just thinking--"
"Will everybody just shut up." Mabel came up behind them. Fishing gear, laced haphazardly, hung around her.
When we continually use she 'laughed' or 'he nodded' as an easy dialog tag, it becomes devalued. This is a pity, because these are strong words if we save them for the right moment.
Mabel pushed the last of the hacked and bloody body parts through the hole in the ice.
"Cherries, anyone?" She laughed.
