UK is famous for having extremely tough zoning laws, with many, many buildings being listed / landmarked. Something that does run very well in the UK are stores like Greggs which are usually classified as small shops (cat. E) without a kitchen. So the analysis applies there as well.
transaction fees are not increasing though, so they can't offset miner rewards. they have been in the $100k-$200k per day range for a long time, with only occasional breakouts: https://www.blockchain.com/explorer/charts/transaction-fees-... and the trend is not to the upside. in fact with the arrival of ETFs in 2024 the trend is clearly downwards.
This can have another explanation as well: the moment a block is found, the miner starts building on top of the previous block but hasn't constructed a new full block of transactions yet as that costs a bit of time to calculate and distribute. In this period, a new block could be found.
Blocks are Merkle trees, only the head transaction contains global seed. So, for one to mine block, one needs to walk Merkle tree up from head and then finish work with small amount of data in the block header.
Thus, the time spent mining block is directly dependent on the logarithm of number of transactions in the block.
If one can mine a block with 3000 transactions (11-12 hashes to the header) in 10 minutes, one can mine a block with one transaction (1 hash to header) about ten times as fast.
The construction of the block is negligible if we talk about complete block mining time.

Huh? Surely the attempts for both take exactly the same amount of time after you've initially constructed the block, you're calculating only a single hash for each attempt.
Not downvoting you but such a broad statement is pretty meaningless if you don't segment by age group. Also Tiktok captures almost the same percentage of US ad video spending - that wouldn't be the case if youtube had so many more viewers that matter to advertisers.
The feedstock has to come from somewhere, right? I’m assuming many farmers would prefer feeding it into stable vats of algae or fungus than dealing with the risks of another epidemic-induced chicken cull.

Many farmers don't have the financial means to redesign their entire pipeline to move from birds to fungus. "farming" is in the name but I also suspect there is nothing in common between raising chicken in cages and mushrooms in sterile containers in term of know-how, maintenance, &c.
Factory farms consume far more feed than they can grow on site though, so the real power isn’t in the chicken farmers, it’s the ones growing chicken feed, and they’re probably used to switching crops to suit market demands.
And the farmers who do grow their own feed are probably smaller operations targeting higher quality meat than factory-farmed chicken, so they’re not the ones that vat-grown meat-substitutes would be competing with.
Alternatively, one of the poultry meat giants will just buy it and produce it themselves so they can capture the vegan/vegetarian market too. Why compete when you can consolidate?
Microsoft is using them in order to be better positioned than other big players, and they succeeded, even if Google is now starting to catch up. They can withdraw their support when and how they see fit, own exclusive IP rights to OpenAI's models and the hardware is their own anyway. They only lack the researchers, but they'll then be on the market.
There's also a possible scenario where the online ads market around search engines gets completely disrupted and the only remaining avenues for ad spending are around content delivery systems (social media, youtube, streaming, webpages, etc.). All other discovery happens within chatbots and they just get a revenue share whenever a chatbot refers a user to a particular product. I think ChatGPT is soon going to roll out this feature where you can do walmart shopping without leaving the chat.
This is unrelated to the cloudflare incident but thanks a lot for making that page. I keep checking it from time to time and it's basically the main data source for my long term investing.
