The answer to this question depends on how we define "deterministic" in the context of communications technology.
If we define deterministic as the degree to which communications technology can operate autonomously, without human intervention, then it's true that recent advances in technologies like artificial intelligence have enabled a greater degree of automation in communication. For example, chatbots and virtual assistants can now handle many routine customer service inquiries without the need for human operators.
However, it's important to note that these technologies are still ultimately programmed and designed by humans, and their actions are limited by the rules and algorithms that have been programmed into them. They do not have true autonomy or the ability to make independent decisions outside of their programming.
On the other hand, if we define deterministic as the ability to predict or control outcomes in communication, then it's less clear that communications technology is becoming more deterministic. The internet and social media, for example, have opened up new channels for communication that are highly unpredictable and can be difficult to control. While algorithms can be used to shape the content that users see, it's often difficult to predict how users will respond to that content, and there are still many unknown factors that can influence the success or failure of a particular communication.
In summary, while recent advances in communications technology have enabled greater automation and control, it's important to recognize that these technologies are still ultimately constrained by the rules and algorithms that have been programmed into them, and that the unpredictability of human communication remains a challenge for these technologies to overcome
