Why this letter was written

What prompted the letter

The letter places reported action-recognition results alongside the quoted description of V-JEPA as a step toward a more grounded understanding of the world.

Why this matters to readers

Readers need to see how an account of performance on a specific task connects to a broader claim about understanding.

What the letter asks

The letter asks for the criterion connecting the two and an explanation of why it applies here. It also proposes keeping that criterion and its written justification open to examination.

The letter

Transcribed from the supplied screenshots. Screen line breaks are joined into paragraphs; wording and punctuation are retained.

Dear Professor LeCun,

Meta’s article of 15 February 2024 quotes you calling V-JEPA “a step toward a more grounded understanding of the world”.

Please indicate the criterion connecting the reported action-recognition results to that formulation, and the grounds for applying it here.

beforeword proposes keeping three elements separately inspectable: what is written, what it is read as showing, and the grounds offered for accepting that reading.

Here, the proposed examination concerns both the written account of task performance and its interpretation as progress toward understanding.

The criterion and its written justification remain further formulations whose interpretation and grounds can also be examined. The same examination applies to human self-descriptions and to this letter.
