Yes there are some laser counter measures being tested, but there is no way we are going to be able to reliably swat down handfuls of these things arriving on target at once.
Once they are cheap enough and China decides they are willing to sell them to anti-western regimes, the era of the air-craft carrier as a means of force projection is over. It won't be possible to park anything that big in hostile waters, at least without total sat-nav jamming in effect.
Everyone one bitching about Iran right now, needs to realize this was the final opportunity to leverage our force projection capabilities to break the back of adversary that has thwarted our policy efforts in the Middle East for decades. Yes its a mess, but the world is going to become a much much scarier place, where the Pax Americana cannot but sustained, and taking Iran out of it as a major power before that happens makes it just a little less scary.
Of course Trump and Hegseth will never say this because it is not raw-raw USA! Its not flex, so they can't admit it. Reality is though any regime that can scrape together a few million to buy some handfuls of missiles will be able to bite their thumb to any "Super Power" they wish.. Asymmetric warfare will now be so asymmetric no military budget however out sized will over come it.
