AI’s biggest hurdle is human, former LinkedIn HR chief says at Lisbon summit

What happened

Steve Cadigan, former chief human resources officer at LinkedIn, told the Portugal Digital Summit in Lisbon that companies rushing to replace employees with artificial intelligence risk undermining the productivity gains they hope to achieve. He argued that AI’s greatest challenge is human, not technological. Essential Business reported the remarks on 23 October 2026.

Why it matters for international residents

International residents working in Portugal may see AI adoption affect hiring, job roles, and workplace training. The warning suggests that workforce decisions around AI are not only technical but also organisational and human. For those in HR, management, or technology roles, the debate is a reminder that productivity outcomes depend on how change is managed, not just on the tools deployed.

What to do next

• If you are an employer or manager, review AI plans with attention to staff impact and productivity outcomes, not only cost reduction.
• If you are an employee, keep informed about how your organisation is using AI and what training or support is available.
• Follow updates from the Portugal Digital Summit and business media for further details.
