For sure Freud and modern therapy as practiced today are very different. Freud influenced the language, structure, and goals of talk therapy more than the exact methods most therapists use now. Modern therapy kept many of his clinical observations about inner conflict and relationships, but dropped or revised a lot of his more speculative theory.

Since mental illness or other trauma is entirely contained to the brain, you can in fact say that the problem is entirely biological. We are starting to see the tech industry make real inroads to biology. Neuralink, gene therapies, AI designed drugs, etc. All of these innovations will decrease the need for therapy, which at best you can say helps people learn to live with conditions, but never permanently fixes the problem.
