interpretation

Read the experiment before the headline

Identify the task, hardware or simulator, scale, accuracy and classical baseline. Check whether time and cost include preparation, repeated shots, error handling and reading the answer. A faster subroutine need not make the whole workflow faster.

interpretation

Separate result, target and business

A paper can establish a result under stated conditions. A roadmap describes an intended future. Revenue requires a paying customer and accounting recognition. Those three kinds of evidence answer different questions. Ask what additional result would change your assessment.

Check your understanding

Does a peer-reviewed result prove that a business is profitable?

Reveal the answer

No. Scientific evidence and financial evidence need separate checks. A technically interesting result can still be costly, narrow or commercially premature.
