Nikesh Arora, CEO of Palo Alto Networks, warns that 90% of enterprise workers lack the skills to work with AI, and that technology automation will eliminate half of marketing and HR roles within three years. The assessment signals an urgent need for workforce retraining as companies move from experimenting with AI to embedding it into core operations.
The AI skills gap
Speaking on the 20VC podcast, Arora said 90% of enterprise employees "are not AI savvy." He attributed the disconnect to a lack of training courses. His own 21,000-employee company holds workers responsible for their own development, creating what he called a "Darwinian moment" where firms must identify who can adapt.
Many companies, including SoftBank, Coinbase and Block, have cited AI as a reason for job cuts rather than investing in upskilling. Arora criticized that approach directly.
Attrition over layoffs
Arora took aim at the workforce management strategies of Coinbase CEO Brian Armstrong and Block CEO Jack Dorsey. "They say, 'I can't train these people. I'm going to just find the people who are going to come in and help me do this stuff,'" he said. Instead, Palo Alto Networks relies on natural attrition and hires for technical roles through hackathons.
The company expects to replace 20% to 25% of its team within 12 months. "Give me three years, I'll have hopefully enough AI savvy people working at Palo Alto," Arora said. The firm added 5,423 employees from the end of fiscal 2025 to Q3 2026, according to its latest 10-Q filing.
Marketing and HR face dramatic shrinkage
Arora's three-year rule is blunt: companies will likely have half the people in roles like marketing, HR and finance. "My biggest problem in marketing is I have 600 people, but I'm not sure they all fully understand how to consistently deliver my tone of voice," he said. Advanced AI applications can now be trained on a company's voice to handle much of that work.
For HR professionals, this means building expertise in AI for Human Resources is no longer optional-it is a condition of staying relevant. Marketing teams face similar pressure, with Arora singling out the difficulty of getting 600 people to deliver a consistent brand voice. Upskilling in AI for Marketing could be the only long-term path forward.
Despite the tough outlook, Arora dismissed fears of widespread job losses. "I think there's this fallacy people believe we're going to have less people working because AI is going to take over our jobs," he said. "I don't believe that. I think what's going to happen is you can't imagine the number of people on my team who want more technical resources, more AI-savvy resources because they want to do exactly these things."
Why this matters for General, IT and HR professionals
The warning from a CEO at the center of cybersecurity and AI adoption is a concrete timeline, not speculation. If marketing and HR departments could halve in three years, the only safe move is to develop AI skills now. For IT professionals, the demand for AI-savvy talent means roles will shift toward implementation and oversight of automated systems. HR and marketing staff who build fluency in AI tools will be best positioned to keep their careers on track.
