Do you think that if something is written in the paper or on the class
slides it makes it immediately valid and sound ?

https://en.wikipedia.org/wiki/Anycast

Please read the wikipedia:

"Anycast is a network addressing and routing methodology in which a *single
destination address* has multiple routing paths to *two or more endpoint
destinations*. Routers will select the desired path on the basis of number
of hops, distance, lowest cost, latency measurements or based on the least
congested route. Anycast networks are widely used for content delivery
network (CDN) products to bring their content closer to the end user."

And IP anycast is used far much broader and wider then just for DNS root
servers.
