Here's a thread on a few (of many) reasons why Bitcoin mining is *not* doomed:
1) Hardware manufacturing
2) Mining as an operation
Over the last 5 years, ASIC replacement cycles have lengthened significantly. In the early days, they were short, with designs obsolete within months. Companies like Bitmain could iterate rapidly since mining was lagging behind the latest tech node.
At nearly every stage of the hardware supply chain, the competition is lowering the risk of monopolies.
This a promising sign for Bitcoin.
Assuming 2 year hardware depreciation and a trillion dollar Bitcoin network value over 5 years, miners should not be willing to pay more than $7.5 billion for equipment annually.
Discounting to today’s $150 b in Bitcoin network value, the total EV attributable to mining OEMs shouldn't exceed $5 b.
As the industry has professionalized, mining operations have changed substantially. Mining data centers are now industrial-scale facilities with management and servicing on par with traditional cloud data centers.
Electricity is a critical consideration in the economics of mining facilities
It will be harder to obtain large amounts in any specific region and regions that have historically capitalized on energy arbitrage opportunities will no longer.
These players will pump major $$$ into it. (think investment banks and traditional peaker plants)

Bitcoin mining will be the ultimate path to direct exposure to this new monetary world order.
