Telepathy might initially seem a much softer, psychological proposition, tainted with a sense of the supernatural. Yet both Campbell and Clarke were lifelong advocates of the view that telepathy was highly probable, the scientific proof of its existence likely just around the corner. The promise of telepathy – soon to be achieved, not far off, only a few test subjects away – feels very familiar when reading Musk’s boosterish announcements on Neuralink’s latest breakthroughs.
The promise that telepathy is just about to be realised is not confined to entrepreneurs and science-fiction writers alone. For more than a century, there have consistently been figures in the scientific establishment who have entertained similar hopes that telepathy would soon reach the threshold of proof, promising everything from opening a new evolutionary phase of human development to a new psychic front in the global arms race.
