What is the future of domains? Will they loose their value?

[glight]

However, the value of domains may change in the future. For example, the emergence of new top-level domains (TLDs) like .app, .shop, .xyz, and others could make some traditional TLDs less desirable, and their value could decrease. Additionally, changes in search engine algorithms, social media platforms, and other online marketing channels could also affect the value of domains.

Traditional TLD getting beaten up by non-TLD's isn't something to be concerned about. And also it is not relevant to OP's query. OP's query is about domaining value as a whole not of a particular set of domains.
