That's a valid question....... 30 years back in time, for someone who was 40 at that time. 20-30 years from now - 50-60 will be very different in many ways, compared to current 50-60. Physically, but that's just one side, another - technologies. You'll be able to have a "companioship" in ways that we can't even imagine currently (probably even AI will be a good friend to have a company, or maybe it will be a better friend than real people, who knows..). Peoples brains are used to thinking "linear", but that's not how technological evolution happens. Life will be VERY different for these who'll manage to stay alive 30 years from this day and I'm confident to say that most uf us aren't able to even imagine of HOW different it will be. From heart transplants, grown in a lab, to brain regeneration, stem cell therapies, full immersion virtual reality, etc... just earn some fukkin money, that's what a main goal must be for these who are afraid of becoming "lonely".
AI companionship is and will always be for losers, or nicely put, those who cannot connect with other people. Who wants fake, when you have the real thing? Oh, I get it, a person wants to have something that will only think like they want, and won't have their own desires. There was an article on AI "companionship" awhile back and they talked about the real sick side of it, which will no doubt come into play, because they represent what sick humans wants.
Humans haven't changed much in their wants and desires from 2,000, or 5,000 yrs ago. We all want power, to be loved, wanted, desired, or admired.
