Humans are about the most vulnerable thing out there. Yet nobody suggests that we should get rid of the infantry because they're too vulnerable. Instead, we give them camouflage gear, some armor, train them to stay behind cover and move carefully, and work on better medical care if they get hit.
FWIW, hypersonic weapons are likely overrated. The hard part has always been finding an active deployed carrier and tracking it well enough to guide a weapon into it. If you can do that, there's no shortage of weapons that can sink it. The carrier's tactics are to use its air wing to stay outside of radar range from any targets while still being able to strike, and using airborne radar as needed to monitor the area without revealing the precise position of the actual carrier.
Foreign militaries are just as prone to exaggerations about how effective their weapons are as American military contractors. Results of well-run tank divisions against anti-tank teams, some of which are documented in the GP's video, show that the kill rates against tanks are often underwhelming even in situations where the tanks are at a disadvantage.
So what does Russia have? Currently, all they have fielded is the Kinzhal missile. But is it neither a hypersonic glide body nor a hypersonic cruise missile. It is simply an air-launched ballistic missile. It would not be suitable for an anti-ship mission, unless striking a ship docked in port. The impressive and novel thing about it is that they managed to get a ballistic missile to be launched from an aircraft, which is rather tricky to do from an engineering standpoint, and IIRC is the first ALBM to actually be deployed. They also have Avangard in development, which is a hypersonic glide body deployed from ICBMs for the nuclear strike mission. Finally, they have the Zircon missile in development, which is a hypersonic cruise missile meant for the anti-ship mission. Russia claims to have completed testing of the missile, but it doesn't appear to have been deployed yet. It's unclear how effective it would be against a carrier strike group, with air defenses, electronic countermeasures and decoys. Notably, it cruises at a high altitude, unlike most anti-ship missiles which try to skim the surface to make it harder to detect and track on radar.
Ultimately, I don't think that hypersonic weapons fundamentally change the security of the carrier. It may necessitate the development of some anti-missile missiles better tuned for the counter-hypersonic mission. It may necessitate altering doctrine towards the anti-ISR (intelligence, surveillance, and reconnaissance) mission to complicate targeting such missiles. I could be wrong of course!
In fact, it looks like the US has 11 active aircraft carriers [1]. It seems that they are all near port right now [2], this might be the reason.

Simple: carriers are for power projection against weaker enemies with low tech militaries. Thus their vulnerability against high tech miliraries is a moot point since wars between high tech powers == World war == unlikely (hopefully).
As an example, is there a point where hypersonic weapons become so effective that aircraft carriers are [temporarily?] retired? Surely the cost (time, money, human lives) that goes into the weapon system is part of the equation.
