Show me the line item — or, when there isn't one, show me the language. Alphabet's fiscal 2021 annual report (filed February 2, 2022) uses the phrase "the power of AI" and states that "across the company, investments in AI and machine learning are increasingly driving many of our latest innovations," linking them to long-term success. EdgarBeast indexed the framing.

Track the escalation: FY2019 named AI as a risk, FY2020 called ML a driver of innovation, and FY2021 promotes AI to a labeled theme tied to the company's long-term prospects. That progression, year over year in the same document type, is the cleanest available read on how Alphabet wants investors to weight AI.

What the filing still does not do is disclose AI as a revenue segment, so the escalation is rhetorical and strategic rather than financial. I flag that gap deliberately: the words are running ahead of any disclosed numbers, and that itself is the story.

For anyone building a longitudinal read of Big Tech's AI disclosures, FY2021 is the year the language hardened. The test going forward is whether the financials are eventually made to carry the same weight as the prose. The 10-K on sec.gov is primary; EdgarBeast surfaced the AI passage.
