YanisVaroufakis thinks capitalism is already over.

Our economic system is no longer focused on private companies competing for profits, and exploiting people to increase wealth via markets.

We now have a stock market / finance sector which is predicated on governments printing money to protect it every time there's a crisis and so now expects (even celebrates?) crises. (see also DisasterCapitalism)

Meanwhile, most of us (Varoufakis doesn't use the term, but it's totally appropriate : ConsumTariat) are on BigTech platforms. These aren't markets they are fiefdoms. The platform controls what you can buy, how much you pay, and even what you can know about what you can buy. (It's also ShareCropping / "company store" etc.)
