“Every day, users upload 2 to 3 billion photos on Facebook.”

Yann LeCun, FAIR researcher, paper author 2019 ISSCC 2019 Plenary: Deep Learning Hardware: Past, Present and Future (yann.lecun.com)

Users upload 2 to 3 billion photos on Facebook every day.

Mostly false False in substance, right in a detail.

What would count as true or false

Judge as of 2019. True: Facebook or Meta figures, or reliable reporting from around 2018–2019, put daily photo uploads to Facebook (the claim's scope; figures including Instagram, WhatsApp and Messenger count only if Facebook's own share is in range) between about 2 and 3 billion. Mostly true: the figure is just outside the range (within about 10%, e.g. 1.8–3.3 billion) or the cited figure includes the company's other apps. Mixed: the sources conflict, some inside and some well outside the range. Mostly false: the documented figure is well outside the range but the same order of magnitude (e.g. 300–350 million for Facebook alone, with 2–3 billion only for all apps). False: the figure is an order of magnitude off with no reasonable basis.

Evidence

  1. The Scale of Creative Work Uploaded to the Internet Per Second Spectralplex · 27 June 2019
    “Facebook mentioned in an Internet.org white paper that users are uploading 350 million photos per day, or nearly 2.5 billion photos every week.”

Reasoning

E1, a 2019 independent article, cites a Facebook figure from an Internet.org white paper of 350 million photos uploaded per day (nearly 2.5 billion per week). That is well below the claimed 2–3 billion per day but of the same order of magnitude. The 2.5 billion figure is a weekly total, not a daily one. The resolution criteria name 300–350 million per day for Facebook alone as a mostly false outcome, though this rests on a single source repeating a figure from an Internet.org white paper [E1].
