Could a skilled hacker given the resources crash the internet itself? With more and more people joining the internet everyday, it would be becoming increasingly easier for hackers to just, overload the internet and crash it, or at least make it become extremely slow to the point it's unusable. I don't even know whether it's possible but it does beg the question, will the internet one day become unsustainable, to the point that it can be abused by hackers and just, crashed?
In theory, the internet would be susceptible to a ddos attack, just like every other thing that revolves around connections. Servers have a finite amount of memory/voices, both of which could be filled therefore crashing/dramatically slowing the internet to the point of connections being impossible. Hopefully this answers your question
Also to crash the internet you would have to attack every single server that hosts a website. You have to infect all of them with malware or a super massive DDOS attacking all IPs
