Would this cost a lot to run the servers (I’ve heard that the AI is resouce intensive). Then is it worth the money?

It's surprisingly inexpensive! Our bill for the last three days (about 8k websites built) was around $75. Definitely more expensive than standard servers, but not too bad.

But cooking and running a restaurant demands completely different skillsets. Being the best cook doesn't always means they can build a successful restaurant business.

This is true. I wonder how servers used to scale very well in the past.
