Can you still get in trouble if you admit poor workmanship long after a company went bankrupt?

Say you work for some company, just for argument’s sake any kind of company, and it went bankrupt. Then like five or so years later you write a book and ramble on how you sucked at that job and didn’t really know what you were doing. Could you still get in trouble in any way even though the company is now completely gone? I don’t mean anything serious like insider trading or anything like that – you just sucked at your job and maybe lied about a few things.
