I'm not. It's only a matter of time before some rich asshole starts shooting at the whales, dropping sticks of dynamite or some equivalent callous and heartless thing. I don't give two shits about the rich fucks, but I am highly concerned about the consequences to the whales. Humans, as a species, have no chill.
You're thinking Bezos yachts, these are $50-200$k boats people use as homes to see the world, not rich people. The word yacht doesn't mean wealth, it's just not a common mode of transportation.
Well the pics are for identifying individuals. The science folk are trying to create a catalog and with that which pods (family groups) are involved, which aren't, and if there are groups who aren't involved, do they become involved in the future due to being taught/learning the behavior.
The ability to manipulate objects isn't really that useful underwater, I feel, apart from being an unprecedented adaptation on the flipper and almost definitely coming at the cost of efficiency while swimming. Everything you want to mess around with as an orca can be transported with your mouth.
Now, sonar loud enough to shatter human rib cages, that's what's going to be the next big step.
For context, not everyone who lives on a boat is wealthy. I live on a 'yacht', a 29 foot sailboat. Your walk-in closet is larger, yet because it's privately owned and not commercial it's considered a yacht.
A 29' boat isn't going to have a 29' liveable area.
First off, a boat narrows so much at the front that a 29' boat is really closer to 25' at best. Then it might be 10 feet wide, so you're looking at about 250 square feet. Most of that is gonna be deck so cut that in half again if you want your living space to be out of the elements.
When you go under the deck you might think there would be plenty of room, but you need to have fuel, engine, generator, bilge, etc.
So in your remaining closet-sized space you need to be able to eat, sleep, cook, use the restroom, store your shit, entertain yourself, etc.
Around here you can buy a serviceable 29-foot sailboat for $5k, and a mooring buoy for $1k. It's cheaper than a van by the river FFS.
People who live on sub-40-ft sailboats are usually just hanging in there. Source: that was nearly me before my fortunes changed slightly. Boats are underpriced because they are a lot of work.
My sister is a corporate executive. Her walk in closet is objectively larger than a 29-ft live aboard. Hell her ensuite bathroom is bigger than that and she lives in a duplex. You are lacking real world context I think.
I wonder how practical it'd be to have an underwater sound emitter to repel one. The use of sonar gets sometimes criticized for its impact on whales. You'd think that you could take advantage of that.

Probably not powerful enough. Looks like military sonar pulls down a lot of power:
The first ship I was on used a sonar system from the ‘60s. The system used the maximum amount of power, just short of causing the transducer (an underwater combination speaker and microphone) array to cavitate (boil the water). As you go deeper, it takes more power to cavitate, so submarine sonars were even more powerful (but seldom used, to keep from advertising their location). Our system used 288,000 watts (A powerful home stereo may use 250 watts, so this is like 1000 home stereos all going at the same time!) When the power supply for the amplifiers malfunctioned, it often erupted fireballs across the room (Our Division Officer was so frightened, after seeing one, that he refused to enter the room, or even come down the stairs to the room’s door!). In addition, besides the raw power, the signal can be electronically focused to go in a single direction, much like the powerful spotlights used for advertising (car dealerships, for example). This makes the signal strong enough, that you can bounce it off the bottom of the ocean and detect a submarine more than 40 miles away.
The sound is so loud, that you can hear it IN THE AIR while near a pier, when the ship was over 1,000 feet away (several city blocks). For a nearby diver in the water, it would extremely painful. In Vietnam, the ships in-port would run their sonars 24 hours a day, to keep enemy divers away from the ships.
Inside the ship, you could hear it, no matter where you were below decks, even in noisy places. Most of the crew hated it. Sometimes, we (the sonarmen) would light-off the system, with the most powerful beam pointed at the rest of the ship, at 6:00 AM for Reveille (“Damned %&$ sonarmen! *%#$%^%$!!!”).
I think we should use AI to decifer their language and send them messages saying, "Chill bro! I'm just passing through." We'll probably get a response going something like, "You in the wrong neighborhood boy!"
The article is about orcas, but that video at the top is not an orca and just happened to sink a small fishing boat while it was feeding. Pretty sure that incident was an accident and the whale wasn't trying to sink it, it was just breaching and eating.
“Ohm's law says that the current is voltage divided by resistance, so 110 volts / 2500 ohms gives 0.044 amps. At first, one might say that the orca would survive since that's less than the fatal level of 0.1 amp. However, that level is easily enough to cause the muscles to contract violently, and if that condition persisted for more than a short time, it would kill by respiratory paralysis. (Again, assuming whale physiology is comparable to humans'.”
