    A building made of bricks lasts much longer than a structure made out of dead trees.

    Unless you live in an earthquake zone. In an earthquake, wood frame buildings sway. Brick buildings fall down.

    In the SF Bay Area, brick construction is banned. If you see a brick building, it is mostly likely a fake facade on a wood or steel frame.

    I bet the time can be changed to allow longer use of the old firmware...

    It uses a smartphone as the GUI for the controller, so it can pull the time from the cellular network.

    The drone also has a GPS receiver, and can get a timestamp from the GPS satellites, accurate to within 40 nanoseconds.

    Being the military, they can build (or contract out) their own.

    The F-35 took 26 years to go from contract to production, and will cost a trillion dollars. But drones are props rather than jets, so maybe the V-22 Osprey is a better comparison. It took 32 years, and cost $36 billion.

    Unless they have an unlimited budget and are building it for their great grandchildren, they need to go COTS.

    Anyone know how the kill is implemented?

    I have DJI Mavic, not a Spark. Mine uses a smartphone as the controller GUI. When I connect my phone to the drone controller, the app will sometimes, but not always, check for updates. If an update is available, it is downloaded and installed, without any opportunity for opting out. Some of the downloads may be legally required, such as data for restricted airspace. Others, as in this case, are safety issues, so I don't see why anyone would want to opt out, or why anyone should be allowed to, since they may be endangering other people.

    Nitpick: The headlines use of the work "brick" is misleading. The drone cannot be flown until it is updated, but it is not "bricked". As any true nerd knows, when something is "bricked" it is permanently and irrevocably disabled, which is not what this is.

    What is the alternative? The DJI drones are a generation ahead of anything else on the market ... and with an 85-90% market share, they have enough revenue to extend their lead.

    Disclaimer: I have a DJI Mavic Pro. It is very nice.

    People just valued cheap more than they valued safety.

    People are very bad at understanding risk. Product liability laws shifted the cost from injured customers (who are poor decision makers) onto the bean counting accountants and lawyers at the auto and insurance companies (who are good decision makers).

    The auto companies could then either make their products safer or pay higher liability payouts. Either of these will mean higher prices for consumers, who can then make a rationale choice since the "cost of risk" is incorporated into the sticker price.

    The business model should include protecting people and pedestrians at all cost.

    If you want to be taken seriously, try to avoid hyperbolic phrases like "at all costs". In the real world, resources are always finite.

    A car that protects itself while getting everyone killed probably won't have a great used car value.

    Killing a human will cost millions or tens of millions in legal fees and payouts. Suggesting that these cars will intentionally prioritize avoiding mechanical damage over human life is absurd.

    The US does not employ landmines anywhere other than the Korean DMZ. They are used there because North Korea also uses them, and removing them would require increases in other capabilities.

    This reminds me of what I've gone through with bison. Two years ago I was buying it for $5/lb.

    Bison is typically 2 to 3 times the price of beef. I have a friend who tried to raise them in Wyoming. He installed powerful electric fences, and still had problems with them breaking through. Cattle can be artificially inseminated, but bison cannot, so he kept a few bulls, which are big and mean. Loading a herd of yearling bison into a truck to go to the slaughterhouse can be ... challenging, and not so good for the truck.

    There are some advantages. They can graze on crappy pasture contaminated with locoweed and other stuff that cattle will not eat. They also have no problem enduring harsh winters and will paw through the snow to reach grass.
