One of the defining features of many such people, by nature or disposition or practice, is they are not easily able to offer in return the meeting of the same needs in another person. At least, not in a way that's easy to understand. People do not gravitate to what is or seems to be one-sided. It seems they are still wired to want a certain level of attention, though, so it's not as though we can just pair them off and expect it to work. What they want and what they can give are not in balance.
Counseling can help with this to some degree and everyone can make some amount of progress. The question is what we do with those whose "ceiling" remains lower than is tenable for most relationships. For those, there is not a better solution than robots.
However, the always-available, always-validating robot is not a valid psychological need. It is a supernormal emotional stimulus. It is not healthy and, like other supernormal stimuli, builds invariably tolerance, desensitization, and dependence. Fast cycling of discontent -> open app -> validation is a huge contributor, the same way that the constant availability and instant nature of vaping make it incredibly addictive.
