Gold and Bitcoin have their own segments. Gold investors are usually people who do not understand or are skeptical of cryptocurrency
But what will happen when the future generations who understand Bitcoin replace the people who do not understand Bitcoin
for bitcoin to be adopted more it doesn't have to replace anything specially not something like gold!
if your arguments were about bitcoin replacing banks and traditional financial systems then your arguments would have made more sense compared to now that you are insisting on comparing bitcoin with something that doesn't even fall under the same category as bitcoin (ie a currency).
