Has the US effectively undergone a coup?

I came across this Q&A recently, starring a historian of authoritarianism. She says

Q: "At what point do we start calling what Elon Musk is doing inside our government a coup?"

A: As a historian of coups, I consider this to be a situation that merits the word coup. So, coups happen when people inside state institutions go rogue. This is different. This is unprecedented. A private citizen, the richest man in the world, has a group of 19-, 20-year-old coders who have come in as shock troops and are taking citizens' data and closing down entire government agencies.

When we think of traditional coups, often perpetrated by the military, you have foot soldiers who do the work of closing off the buildings, of making sure that the actual government, the old government they're trying to overthrow, can no longer get in.

What we have here is a kind of digital paramilitaries, a group of people who have taken over, and they've captured the data, they've captured the government buildings, they were sleeping there 24/7, and elected officials could not come in. When our own elected officials are not allowed to enter into government buildings because someone else is preventing them, who has not been elected or officially in charge of any government agency, that qualifies as a coup.

I'm curious about people's views, here. Do US people generally think we've undergone a coup?
