The comparison is a bit unfair because the technology of 1957 was primarily analog. A few rolls of film can store the same HD videos as an iPhone for instance. Video phones existed in the 1960s and just didn't catch on.
It's sort of an apples and oranges comparison. Obviously there are many things that couldn't be done with analog tech. But it's not as bad as you would expect with just naive comparisons based on the cost of vacuum tubes.
