## Why Attend?

🌍 The digital economy already makes up nearly 10% of Hungary’s GDP, yet ICT specialists represent only 4.2% of the workforce, well below the EU average. Hack4Earth brings together innovators to bridge this gap, tackle the energy footprint of AI, and empower Hungary’s technology sector to lead in sustainable solutions.
