Today: the five AI headlines of the day → and the AI Wiki

What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

What this does not establish

The comparison is reasoning versus non-reasoning assistance, not AI versus classical search, and does not transfer automatically beyond travel.

Counterevidence & uncertainty

More informative assistance increased chat engagement while reducing search-driven purchase, contradicting automatic conversion-lift assumptions.

What would change the reading

Track replication, revised versions, denominators, confidence intervals, platform changes and deployed commercial outcomes.
