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.

MWITA-CR-2026-0019 · Evidence B · P0

MCP und A2A standardisieren Tool-/Datenzugriff beziehungsweise Agent-zu-Agent-Kommunikation, lösen aber fachliche Semantik, Delegationsrecht, Haftung, Vertrauen und Erfolgsbewertung nicht.

Counterevidence & uncertainty

Künftige Profile/TCKs können mehr Semantik und Security standardisieren, aber fachliche Autorität bleibt domänenspezifisch.

What would change the reading

Breite, unabhängige Cross-Vendor-E2E-Interoperabilität schließt nachweisbar Authority, Liability, Receipts und Domain Semantics ein.
