Gold might be out of dated by then and crypto might replace it, or not.
Even in the best case scenario for Bitcoin, I don't see it swap position with gold. It's too well adopted and respected for what it is, and then we have its physical nature also playing a role of importance for people.
Gold in physical form is just as decentralized as Bitcoin is, just less convenient to deal with on a daily basis. Another thing is that you can't fork gold to create money out of thin air, which is possible with Bitcoin.
The downside of Bitcoin's forks are that they compete for the same hashrate, which I always found to be a major downside. It caused problems where there wouldn't be any if forking wasn't a thing. It's really unfortunate.
