How much bitcoin will be lost if mined?

As a keen observer of the cryptocurrency market, I'm curious about the potential losses associated with bitcoin mining. Given the finite nature of bitcoin's supply, how much of this digital currency is essentially lost forever due to various factors such as lost private keys, mining errors, or simply being unclaimed for long periods of time? Is there any way to estimate these losses? Could these unclaimed or inaccessible bitcoins potentially pose a risk to the long-term stability of the bitcoin economy? I'd appreciate any insights you can provide on this intriguing aspect of bitcoin mining and its potential implications.
