"Freelancing Career" is a very general phrase, I assume.
If you mention a specific skill e.g designing, writing, translating, etc, or a specific platform like Upwork or Fiverr, the answer can be always YES, because there is always an end to everything and the world is changing so fast; However, talking about freelancing only as a specific type of working, I believe that most of the in-site jobs will transfer and change to hybrid jobs and then freelancing.
People will understand the convenience of flexibility of this style of working and consequently its outcomes!
So I believe NO, even if something changes even as important as the basics, the freelancing career will last forever and will be sustainable.
