That is not true. It takes a lot more than a bootcamp to be useful in this space, unless your definition is to copy-paste some CDK without knowing what it does.

If by useful you mean "useful at generating revenue for AWS or GCP" then sure, I agree.

These certificates and bootcamps are roughly equivalent to the Cisco CCNA certificate and training courses back in the 90's. That certificate existed to sell more Cisco gear - and Cisco outright admitted this at the time.
