Cannes: AI Transformation, Backstage Focus on Costs

At the 2026 Cannes Lions festival, public presentations promote AI-driven transformation, efficiency and orchestration, but informal off‑stage conversations among marketers and agency leaders are centering on the real cost of making AI work. Attendees described rising token and infrastructure expenses, the reality that AI often augments rather than replaces engineers, and the shift from theoretical ROI to line‑item procurement conversations. Speakers and sources at Cannes — including ad tech and agency executives, brand CMOs and analysts — said clients now expect transparency about where AI is used but are less informed or willing to discuss ongoing operating costs. The piece frames this backstage debate as a preview of next year’s on‑stage agenda as use cases move from experiment to sustained production and procurement decisions become decisive.

AI Creative Tools Converge into Automated MCP Pipelines

Three AI creative advances this week illustrate a shift from standalone tools to an automated, composable creative pipeline. Google redesigned Stitch into a full ‘vibe’ design tool; Remotion reached 150,000 installs as a Claude Code skill for generating video from text; and Blender MCP hit 17,000 GitHub stars for building 3D scenes via conversation. All three connect through the open MCP protocol, enabling designs to flow into code and video in one chain. The author highlights DESIGN.md — a markdown-based spec — as the lossless glue for composing tools, and describes scheduled "creative cron job" workflows that run pipelines unattended. The piece argues the deeper structural change is convergence on a command-line interface for creative tools, which will alter product team roles and creative production workflows.

Brands Stuck in Siloed Ads as Journeys Converge

Kristin MacGregor, Global Chief Commercial Officer at Smartly and a former Google Managing Director, argues that rising consumer convergence between social feeds and connected TV (CTV) requires brands to stop treating channels as isolated silos. As multi‑screen, always‑on journeys grow (the piece notes that by 2025 nearly four in five adults will use devices simultaneously), many marketers still replicate identical creative across CTV and social instead of adapting assets to each context. MacGregor highlights that only 16% of marketers use identical assets across channels, calls for “smart adaptation” and an approach she terms “intelligent, infinite creative,” and says AI and creative automation can scale high‑quality variations while preserving brand governance. Smartly cites a case where creative automation helped The Times double campaign cost‑efficiency, illustrating measurable ROI from tailored creative strategies. The article frames the shift as strategic and economic, emphasizing cost barriers for bespoke video variations and the performance gains from smarter creative workflows.
