I take a different outlook. If it 100% went to that landfill site, the chances are very good, if you have the resource to search every possible piece of rubbish. He is talking about AI to help speed up search. Hard drives are surprisingly tough. Some of the platters are actually quite thick and hard to break. Yes some of them shatter easily, but some are thicker. Hard drives are both fragile, and tough. Fragile in that the mechanical arm/seek stuff can break down easily, but the actual platters can be fine. Different drives that are similar can be borrowed for the PCB/electronics to aid recovery. There are lots of methods. He could use specialist recovery firms such as the guy in the youtube vid.
There is every hope they could be retrievable. People want him to fail because people naturally hold no sympathy for others winning like on the lottery etc.
Iirc, when this story first came out, I'm sure he said it was an old laptop drive - those are the ones that shatter most of the time, I guess the platters in them are either thinner for weight savings, or made from a coated glass/plastic.
I don't get his whole claim that AI is going to given them an area to dig - one would assume that the "AI" needs to be fed variables to make a suggestion; such as the date it was disposed of at a tip, the date it was taken to landfill, location etc etc etc - but surely, if the Council make a mistake with any of that data, his AI hopes are dead in the water.
I haven't followed the story religiously - but has this chap even given his wallet ID or anything to backup his claim that there are these millions buried out there? Or, because it is offline, does it work differently (I'm not a Crypto bro)?
I'd love to see him recover the funds, but it has always sounded like a complete lost cause since day one, and the recent threats about sueing the Council, just make him sound like an utter **** if I'm honest. I cannot imagine what it must feel like, to know that a life changing amount of money, that's yours, is buried away somewhere - and I myself would probably want to dig it up too. But it got thrown in a tip - as soon as it leaves your hands, you sort of lose any claim on it. I binned some old bike leathers a while back, would I be allowed to sue the Council as I now want them back?
I appreciate this is a sweeping example, but it feels like that's the straw he's clutching onto now, along with the whole defence that his other half binned it without his consent etc, how are the Council to know that? They just provide the tip, what gets thrown away shouldn't be any of their concern imo
