I think BTC will more likely be added to the 'store of value' items along with Gold, it won't replace gold.
Also, within the crypto world it's very easy for all of us to see that BTC has the properties of gold, it's scarce, it holds value the best in a declining crypto market etc.
But for the general public to accept BTC as gold is a much tougher sell.
It has no physical properties, it has no real world 'uses'.
For the average non-crypto person to accept that some bit of computer code has been programmed to create digital scarcity and that the resulting product is highly valuable is a very difficult bundle of concepts to wrap their head around. The elevation of bitcoin to the status of gold i think will take a generation for people to accept.
