More then 7 tx/s would definitely be nice. But problem is going even to 500 would probably need a complete redesign. But without a redesign new chains will technologically get better and better and the gap will widden. Not sure how long will the gold narrative last....
New chains are not technologically better. They are faster ... but less secured. They achive better scalability at en extend of decentralization. BSC for instance has only 21 validators. So 500 tx/s does not complete redesign ... it needs bitcoin to resign from current level of decentralization (I hope to never see that because we need 1 super secured chain without compromises to store wealth in it).
How long will gold narrative last? Well its not going anywhere. Inflation is going up, printers doing brrrr, cbds are about to be lauched. We never needed btc as much as we need now. Gold, as store of value narrative, is here with as for millennia starting from antiquity. Now bitcoin presented more scarse, easier to transfer, simply better solution. I dont think it will change anytime soon.
