Castles come up for sale fairly regularly in the UK. They are (generally) relatively inexpensive to buy, but ruinously expensive to renovate and maintain.
Castles became star forts, with stone/brick augmented with massive amount of earth. These were relatively effective against artillery into the 20th century.
The same way they do with Google Ads - they won't. In my experience (with small companies) most people running ads have little idea what they are doing and don't monitor the results.
>In a world where agents are searching, building, and signing up for services, how do you advertise your product?
I've been running a 1-man software business for over 20 years and it is getting increasingly hard. I no longer get impressions from PPC Ads unless I bid so high that I make no profit. Magazine ads aren't really a thing now. The AIs are stealing my content and SEO works less and less. The channel is being flooded with low effort slop. Traffic to my website is steadily going down. It is hard to know what to do about it. Maybe I can buy some clicks from ChatGpt ads at a price where I can make profit, before the prices rise out of reach?
Well done to the journalist that uncovered this. Makes a change from copying and pasting press releases that many 'journalists' seem to do these days (partly because journalist organizations have been so hollowed out by Facebook et al).
I remember seeing something similar to https://www.jasondavies.com/maps/voronoi/capitals/. But the areas were weighted by the populations of the capitals. You ended up with something quite close to real political maps IIRC.
