Newspaper ad revenue has simply collapsed (https://www.pewresearch.org/short-reads/2023/11/28/audiences...) and it's not being replaced by digital media as digital ad revenue for news industry (as opposed to total digital ad revenue) is shrinking every year.
It's well established that with an appropriate warrant, LEO have always been able to come into your house without telling you and add hidden surveillance bugs to listen on your communications; they have always been allowed to physically modify or replace your phone (e.g. physical phone wiretaps a century ago); Electronic Communications Privacy Act reasserts that this applies also to electronic surveillance and digital communications; so (as a non-expert) I don't really see why that wouldn't apply to smartphone exploits as well. We do see exploits being applied to devices in LEO possession (e.g. https://www.theverge.com/2021/4/14/22383957/fbi-san-bernadin... for one random example) to recover evidence.
The main restriction is the constitutional limits of 4th amendment which requires specific warrants for each case - which is a significant practical obstacle, so the circumstances in which warrantless wiretapping is permitted (e.g. by PATRIOT act) is a contentious issue; however, it's not relevant if a proper warrant is obtained.
Even in USA that likely could be legal with an appropriate court warrant, and many other countries have more permissive constitutions.
If bullets could leave the factory and magically fly straight at your soldiers, expensive single-use ballistic plates would not be a practical solution - you'd simply run out of them as you can't possibly produce as many of them as the enemy can make bullets.
That being said, the air situation is generally improving because of people getting wealthier. Because air cleanliness is local, it matters much more where pollution is happening than how much pollution is happening, as e.g. indoor wood burning for cooking or warmth affects you much more than a much larger pollution through a power plant, and improved technology also makes a big difference even if you're burning the same quantity of the same thing.
In developed countries, air is cleaner than ever - London had notoriously unclean air, being the center of the industrial revolution, but looking at current data (e.g. https://en.wikipedia.org/wiki/Air_pollution_in_the_United_Ki...) 2000 London had immensely cleaner air than 1900 London, and 2024 London has much cleaner air than 2000 London. Similarly, while global deforestation matters for global issues like climate change, in developed countries there is no deforestation - Europe has reforested in the last century, increasing its forest cover, and USA has kept a rather stable forest area over the same time.
In developing countries, the industrialization does come at a cost of local air pollution until the country's wealth grows enough that they "choose to buy the luxury of clean air" by changing local laws to favor more expensive but cleaner ways to do the same thing. So currently the most polluted air is in places like Bangladesh and Pakistan, but there's a clear path for improving that when they come to prioritizing that - because it's inherently some tradeoff between the material welfare of your people and the physical welfare of air quality, because poverty can kill or hurt as much or more than polluted air. That being said, e.g. China seems to have peaked at its local air pollution and is expected to get cleaner air over the coming decades - it's not "running out" of clean air.
I.e. do a simple method but calculate the total energy at the beginning, and at each step adjust the speeds (e.g. proportionally) so that the total energy matches the initial value - you'll still always get some difference due to numerical accuracy issues, but that difference won't be growing over time.
"Tomorrow" your desktop computer might be twice powerful but at the same time the "good model of tomorrow" will be four or ten times larger - I'd expect that the gap between what can be done locally versus what is offered as a service will grow, not shrink.
If the device was solar instead of diesel, that wouldn't move the needle on the dirtiness of the crops. Even the pollution from wear&tear on tires and brakes is more relevant than fuel - we worry about fossil fuels due to the global effect of greenhouse gas emissions, we also care about people breathing in small particles from diesel exhaust, but it doesn't really harm food in farms.
Also, robot arms can be a quite expensive way of doing things; I saw a prototype that used tethered drones (like the common quadcopters, but power and data comes over a cable) to manipulate things as apparently it was like 10 times cheaper than a robot arm capable of reaching the same distances and transporting the same weight payload.
