05 / Speaking & writing

Talks from the frontier.

On adopting AI with eyes open: what it costs, who it affects, and where it should never be the shortcut.

Talk 01Responsible AI

The DEEP problem with AI

Data
Loss of control and agency.
Environmental
Offsetting AI’s compute footprint against sustainability targets.
Ethics
Transparency, trust and fairness.
People
Role anxiety, and growing scepticism about how deliverables were made.

Talk 02Responsible AI

AI is the new plastic.

Makes the case for committing a share of measured AI savings to sustainability.
