Retrofuturism is not the point of this show. It's just a device to explain why the future is not as interesting as they thought it should be in the fifties. The reason that future never worked out is because that is not the way that it was meant to be. But in this show let's assume they got the future they wanted, which caused them to miss out on the future we take for granted today, 70 years later.
This is why the social, political and economic turmoil of the sixties through 2010s never happened and things are as boring as they are; their vision of the future solved a lot of those problems for them. But it created a utopia that seems lame because it lacks all of the conflict and drama that we're accustomed to.
It is no different from a lot of science fiction shows. The future isn't all that interesting. What is interesting is how people deal with conflict, turmoil and collapse. This society has no global warming. It doesn't have opioid addiction. It doesn't have mass shootings. Racism does not exist here. It doesn't have a lot of things. So yes it's boring, but that is what happens when technology solves our problems. It is the reason why they're selling empty promises of the moon, because despite their technological advances, they are missing something deep down. This is a human condition that technology will never address.
