Is high technology only a coveted thing in the Milky Way Galaxy due to the disconnection with the divine realm, because this is a poor substitute for the faculties available to light beings not encumbered with dense physical existence?

This is very much the case. The technologies you speak of, if you think about what they are, what they are designed to do, and how they work, they are all a form of compensation for being in a physical state of existence rather than in a more free-form higher dimensional energetic manifestation that can move about instantly, even multilocate, see and experience and know things from a distance simply by setting an intention and instantly perceiving what is needed and have the knowledge at hand to advance the goals and aims of the light being. The instantaneous reach of non-local consciousness makes all these things possible. When trapped in the physical, limited by the fragile nature of the physical body needing a protective environment with narrow constraints to stay within a safe range such as temperature, atmosphere, and having shelter from external radiation, and so forth, this is a great constraint, not to mention the senses being so very limited in their range and their acuity. So all the technologies are ways of compensating to obtain information, to share information as done via the Internet and the various ways commercial transactions are arranged without having to travel to a location and engage with a person directly to order a product but to do so remotely and have it delivered through a series of options for transporting physical objects needed to support the physical existence in the form of appliances, tools, furnishings, and so on. When technology is sought as a means of overcoming the limitations of human experience, it is a "false god" because it is turning away from your divinity and the divine promise of an exalted existence transcending the physical—that is your destiny, that is the plan of Creator for you to be raised up and ascend to a higher reality of tremendous potential all from capabilities and energetic expressions you can create simply through desiring it to be so. You do not need gadgets in your future environment, the only problems you have are getting there and attending to what you must accomplish for that to happen. That is a further difficulty of physical existence and once again technology will not save the day. You need a divine partnership to save the interlopers and humanity from corruption, degradation, and disintegration.
