Lasers or anything similar like a rail gun require extraordinary amounts of power to work, and that power generates side effects like heat which strain and damage the current materials that we have and are known.
The physics change entirely when its Air to Air laser defense vs Ship to air laser defense.
There are numerous things that shift the math
1. Speed difference
The Stealth fighter is moving at mach 2
The Ship is moving at 40 mph
A fleeing stealth fighter will be able to fire at the incoming missile far longer
2. Atmospheric difference
At sea level, humidity, salt spray, and atmospheric thermal turbulence absorb beam energy, causing thermal blooming
At Sea Level: Air density is 100%. A 100 kW laser beam diverges quickly and may struggle to keep a tight focal point beyond 3 to 5 km.
At 45,000 Feet: Air density drops by 80% down to roughly 20% and water vapor is almost zero.
3. Missile types and threat profiles
The missile likely to take down a stealth fighter is a infrared air to air missile. They have glass domes that allow light and heat to enter. Thus vulnerable to getting blinded
The missile likely to take down a ship is a hypersonic antiship missile, is likely using a AESA seeker and sporting a extremely tough and heat resistant ceramic dome. You cannot blind a AESA seeker, a ship would need a hard kill and to try to burn through a missile body designed to survive the extreme heat and force of moving at hypersonic speeds at low altitudes.
The physics change entirely, it makes tons of sense from a physics standpoint to have a defensive laser on a fighter jet to defend from air to air missiles. A laser system would prevent infrared missiles from hitting your stealth jets.
While for ships it makes no sense, A laser system can't burn through a hypersonic antiship missile fast enough and will just be a waste.
And before you bring up, muh power the J-36 has 3 engines this is why the chinese put in a 3rd engine inside their 6th gen fighter, the intent of the design was always to install a defensive laser

Irrelevant, lasers move at the speed of light.

THis may all be true, but the problems of heating dynamics remain. A laser cannot requires cooling times for both plane and ship because of heat, which limits the frequency it can be used.

Dont tell me, tell the he navies of the world who have tried and failed to create lasers mounted on ships.
Yeah. Let's not forget that just a year ago, those of us in tech could not conceive of developers getting replaced by AI. Things have come so far since then however that there are multiple studies showing junior developer hiring has slowed down to a crawl.
That's the big question, how prices evolve if LLMs increase supply. Standard economic theory says that prices must collapse. There is probably still a short time of 2-5 years where AI native firms can pocket in quite some arbitrage but I guess markets will eventually figure it out and prices will collapse.
This is not only for law. The same applies to all the other industries where LLMs can be used to automate work tasks.
I agree that prices will go down dramatically in occupations that primarily involve code, words, and numbers - and in general knowing the "rules". But there are so many occupations that will have to wait for AI to enter the physical realm. I also predict that the backlash will largely prevent that from occurring.
That's a problem if you live in a country with politically illiterate voters. That's why education is so important in democracies so people don't fall for such crap
Interesting question. What is work? Is playing with your children work? Is talking to elderly people work? I think a lot of things we have outsourced to "professionals" is considered work now and was considered "just normal life" before.
to me work is anything that i am obligated to do, that i can't say no to even if i'd rather do something else. (and yes, doing housework and raising kids is work, and as a society we should treat it as such. that is, we should recognize that stay at home parents are actually working and should be rewarded for doing so. same goes for caring for other people)
> It's reasonable to assume that if AI drop-in-replaced all those knowledge workers, AI companies could credibly charge somewhere in that order of magnitude, because that's what the market is already bearing.
Future supply and demand will set the price - not what is paid today. If supply by open models is vast and cheap, I can't see that the entire knowledge industry can hold the current size. It'll rather collapse to a fraction of its current value.
I live in Vietnam. Bavet is a popular border for visa runs for expats. Normally, you don’t actually leave the Cambodia border building or you just take a bus all the way to Phnom Penh to wait for a visa was approved.
I was curious about the town, because it’s famous for casinos, scam centers, and Chinese manufacturers.
Interesting, did you take pics? Most living quarters (小区）in China have electrical fences and most windows have been barred. Left over from the 80’s when crime was high. Nowadays the bars prevent pets and children from falling out of the window (plus the cage like construction allows for some extra storage space)
I wrote a quick blog post about my experience and included the photos that I took. I was traveling alone and I knew the area was not safe, so I really didn't take enough photos, but the best one is at the end.
Thank you so much, what a great write up (did you submit it here?). Surprised you took any pictures to be honest. Some great observations! Those barred windows def look familiar. Correction:on a second look, these do not look like the typical chinese square tubing bars!
