The switch away from on-premises servers towards cloud and SaaS made disaster recovery irrelevant, agree or disagree? Discuss in the comments.

SaaS vendors might provide disaster recovery at the infrastructure or application level. However, an organization won't be able to use those capabilities without internal processes + policy in place and periodic practice. 

I guess many answers are not thought through !!
SaaS maybe I agree, but moving to cloud doesn’t reduce the outage risk by any extent, unless multi az, multi region, and in some cases cloud native architecture is used

It appears many of those who agreed haven’t experienced a “cloud outage”. If you haven’t practiced a recovery your outage may last longer than if your application was hosted on-prem

How you do disaster recovery will be different but you still need to plan and practice for various scenarios

I found it very interesting that many agree.

Yes, cloud computing and its different service models present unique enablers that were not available before, but to me things like Disaster Recovery, Emergency Management, Continuity of Operations, etc. are largely organizational endeavors in the field of Risk Management that can be eased through technology, but can not be made irrelevant by it.

To quote one of the online sources - "Disaster recovery (DR) is an organization's ability to respond to and recover from an event that negatively affects business operations."

Moreover, overreliance on [any] technology in service of business functions without [deep] understanding of its limitations could be fraught with dangers.

I think it's important to remember that one thing the organization and its management can't outsource is  accountability.
