Is n8n a good long-term choice for production AI automations?

I'm deciding whether to go all-in on n8n for production AI automations and would love to hear from people who've been using it for a while. How many workflows are you running today? At what point does n8n become difficult to maintain? What are the biggest scalability or reliability issues you've faced? Have you ever migrated from n8n to custom code? If so, why? If you were starting today, would you still choose n8n? As a bonus, has anyone been able to build a sustainable business around n8n (freelancing, consulting, or selling automations)? I'd love to hear your experience.
