In which I lose faith in quantum computing

Quick Overview

The speaker concludes that quantum computing is hugely overhyped, predicting that most commercial interest will collapse in the next few years because real-world business problems are often too basic or too disorganized for quantum computers to offer a meaningful advantage over conventional methods.

Key Points: The speaker moved from initial skepticism to tentative belief, but now believes quantum computing is "hugely overhyped" and commercial interest will collapse soon. Quantum computing's foundational promise rests on established physics, specifically using entanglement to speed up certain calculations, with early use cases including breaking decryption systems, quantum chemistry, and logistics optimization. Despite impressive technological progress, with current qubits reaching around a thousand and realizing first error correction protocols, the speaker sees no appreciable impact on real-world business, stating, "I just can't see that this will have any appreciable impact on realworld business like ever." In quantum chemistry and materials, the speaker asserts that Artificial Intelligence is currently 'eating quantum computing slunch' because AI can latch onto regularities in naturally occurring systems. Real-world logistics and optimization struggles are often due to organizational chaos, exemplified by a study showing airlines do not rationally price flights because 'big airlines make their pricing decisions with several different departments and they pursue different goals.' The speaker believes the main driver for quantum interest is code breaking for governments/intelligence organizations, not business applications, and predicts that smaller nations will back out as devices become more expensive. The ultimate conclusion is that quantum computers will remain research devices, and stocks of companies built on this premise are likely to collapse, with the speaker feeling 'a little silly' for taking so long to realize this.

Context: The video analyzes the speaker's evolving perspective on quantum computing, a technology based on quantum mechanics principles known since the 1970s, which promises speedups for specific calculations like decryption and simulating molecular bonds. The speaker initially saw promise due to technological advancements, such as reaching qubit counts up to a thousand and implementing early error correction, but has since revisited the practical applications and found them lacking for real-world commercial use.
