Sophisticated algorithms need the kind of processing capacity that draws too much costly energy
It appears that many of the “deep tech" algorithms the world is excited about will run into physical barriers before they reach their true promise. Take Bitcoin. A cryptocurrency based on blockchain technology, it has a sophisticated algorithm that grows in complexity, as very few new Bitcoin are minted—through a digital process called “mining". For a simple description of Bitcoin and blockchain, you could refer to an earlier Mint column of mine.
