Don't think about that stuff. What happens in the world is out of control. Enjoy what you have atm.Looks like everyone is going TSMC for their higher-end parts for the next gen cards. While TSMC is increasing capacity and they may not all be using exactly the same node/process, I don't think this bodes well for anyone's supply.
Taiwan getting crushed like a grape between China and the US is also a concerning possibility. Five of six of TSMCs current high-end fabs are on Taiwan and the sixth is on the Chinese mainland (and would probably be siezed in the event of open hostilities). They are building a major new one in AZ that should be operational by late 2023, but if TSMC Taiwanese fabs suffer significant interruption in production, they sure aren't going to be prioritizing video card ASICs.
