The other issue is that object recognition from a camera can never be 100% accurate, therefore any decision on which object to avoid and where to turn in an emergency situation will have a good chance of being wrong, based on weather and visibility.
To get better it would need better training data. However there are always more junior devs creating bad training data, than senior devs who create slightly better training data.
The life duration of a light bulb depends on the thickness of the filament. If you make it thicker the lifetime goes up, but at the same time the brightness goes down. This means you spend more money on power for less light output. Look at this lightbulb that burns for 100 years or so in some fire station, it's hardly brighter than a candle.
On an unrelated note: a lot of medieval rulers and nobles died, because their own family members and many children tried to get rid of them for a more favorable inheritance and more power.
Far cry feels just the same since 3. Same gameplay, different story, different setting. While the story itself is usually good, I don't think it has progressed gameplay wise or in technical or graphics aspects in any meaningful way. Car physics are worse than gta5 which is already out for 10 years or so.
Chatbots doesn't mean that they have a real conversation. Some just spammed links from a list of canned responses, or just upvoted the other chat bots to get more visibility, or the just reposted a comment from another user.
But who wants to trade gold with you if everyone is hungry, has no water or power, is freezing or sick? Gold and valuables are only good of you know the economy gets back to normal, or you have someone who will trade useful stuff for gold.
Also, I don't think the average person has a concept how much gold is worth, or how to check if it is real or not.
It's overrun with drop shippers anyway...
