When your AWS bill suddenly spikes to $69k because some data science intern left a huge gpu backed EC2 instance running in ap-southeast-2 with a misconfigured auto-scaling group, and your CTO is at a "digital transformation" conference, and you have hundreds of angry investors asking why your burn rate tripled, you’ll get it.

Or you need to debug why your Lambda function is throttling and you find out that the CloudWatch logs were never properly configured and you’ve been flying blind for three months.

And finally you have a brilliant idea of hiring a second $150k/year AWS solutions architect so that at least one person can actually understand the bill and they can check each other’s Terraform configs. Suddenly, you’re spending $300k on two cloud wizards alone and the cost savings of "not managing your own infrastructure" are completely gone.

The snide rebuttal basically writes itself.
