Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-10-31).
It is a direct quote from Coinbase head of platform Rob Witoff, 'told Cointelegraph': 'And close to 100% of our code, probably somewhere between 95% and 100%, is written by or with LLMs today.' The match is exact apart from the leading 'And', which the passage omits.
