It’s too early to definitively judge this prediction against its own time horizon.

• The claim was about “the next few years” from August 2024. In ordinary language that implies at least ~2–3 years. As of November 30, 2025, only about 15 months have passed, so the stated period has not elapsed.
• Current data, however, do not match the scenario described. For U.S. remote‑capable (knowledge‑type) jobs in early–mid 2025, about 52% are hybrid, 27–28% fully remote, and only ~20–21% fully on‑site, meaning most such employees still have at least some remote work rather than being primarily office‑based.

• Surveys of employers show rising in‑office expectations, but nowhere near “80%+” of knowledge workers mandated back full‑time. One large 2025 summary finds around 22% of companies fully in‑office, with another ~5% planning to be, and about 40% of workers saying they’re required in the office five days a week—substantial, but still far from near‑universal full‑time office mandates.

• Looking ahead, forecasts suggest only about 30% of companies plan to require five days in the office by 2026, while 88% of employers offer some hybrid option, and surveys still show hybrid as the dominant long‑term model for remote‑capable roles. (secondtalent.com)
• A Stanford / Atlanta Fed survey in 2025 reports that only 12% of executives with hybrid/remote staff plan new full return‑to‑office mandates in the next year, implying most employers expect to maintain hybrid or remote arrangements rather than forcing almost everyone back. (news.stanford.edu)

So as of late 2025, the prediction is not currently borne out by the data and appears to be trending wrong, but because the predictor explicitly referenced a multi‑year horizon that has not yet passed, the status is best classified as "inconclusive (too early)" rather than definitively wrong.
