He thinks physical AI - tractors, trucks, mining rigs - will matter more than software. Here's why he stayed quiet for a decade, and what he sees coming next. https://buildingsaas.co.uk/trigger-dev-n8n-and-make-com-solve-different-problems/ https://buildingsaas.co.uk/trigger-dev-n8n-and-make-com-solve-different-problems/ Sun, 15 Feb 2026 21:54:54 GMT Trigger.dev, N8N, and Make.com keep getting compared as competitors.
