This is THE killer app and few really understand the depth of game-chageyness in my opinion.
I don't know how long this will take to really emerge. But in my opinion this will allow Monero to be Bitcoin's "privacy layer".
Eventually we will see some fairly staunch maximalists starting to wake up to the advantages of letting Monero do this work for Bitcoin thereby allowing Bitcoin to retain it's pristine auditability properties. Keep an eye on Matt O'Dell. He is staunchly anti-shitcoin, but he is also bending over backwards to push BTC privacy. He may be rational enough to realize in the end that Monero really is an exception to the Maximialist's rule.
Monero is poising itself PERFECTLY for this reality. The tail emission, and the king of CPU mining. This means Monero is more secure than the average shitcoin.
I was among the folks who was disappointed that we chose to add the tail emission. In fact I was FIRMLY against it. And still recognize it came at a cost. The biggest of which was the change to the social contract, and putting Monero among the cryptocurrencies that have shown that unlike Bitcoin, the more centralized leadership can change the financial contract thereby putting a dent in the store of value property of Monero.
That said, not only will the tail emission do what it is good for, keeping the mining of Monero rolling, but in the same way that Monero can do privacy on behalf of Bitcoin, Bitcoin can do SOV for Monero. This will leave monero to concentrate on it's killer app feature. Allowing seamless flow between these two currencies will be pretty magical. You can sacrifice auditability and SOV stuff for privacy and then come back as you please.
I have always seen a symbiotic future for these two projects, and am very pleased with the way this is coming together.
Monero is so far ahead of anything else in the privacy game... it will remain useful and valuable for quite a while.
When these realities start to become more obvious to the masses we will start to see fairly significant price moves, IMHO.
