Owning a parrot is sort of like owning a flying toddler with a built-in steak knife that will self-harm if bored enough. They are NOT suitable pets for the majority of people, and far more of them will suffer and die in improper housing than will ever be properly kept. To add to that, many large species of parrots, due to their habit of breeding only after a long courtship, are often bred by keeping them in cages so bare that all they have to do is groom and mate with each other. If they're even captive-bred at all and not taken from the wild. They need a massive amount of attention, a very large enclosure, and an ever-changing supply of toys that will inevitably be torn apart. They are destructive, they can be surprisingly vindictive, and they have the potential to cause serious damage to someone if upset. Plus they scream. A lot. For many reasons. Owning and properly caring for a large parrot is a lifetime commitment that you will have to build your life around. Everyone I know of who properly keeps a large parrot (and there are very few people) has set up their house, their schedule, their everything to keep that parrot happy. They are bad pets, period, and the fact that a few people can keep them happy does not change that fact.
Quail, by contrast, are easily bred in captivity, are happy in smaller enclosures, and, if kept in flocks like they should be, can be largely ignored by their owner. They bond with an owner if given the chance, but don't see the owner as their mate, and can thus be left alone all day. All they need for toys are a sandbox, things to hop on, and occasional things to peck at, they couldn't be destructive if they tried, and they won't send you to the emergency room if they bite you. Nor will they rip their own feathers and skin out if stressed, or bond with you so strongly that they wither away if you happen to die. Heck, with supervision, and assuming the person in question can understand that quail are look-but-not-touch, they'd be good first pets.
If you want something that can learn to talk, there are plenty of robots that do that now.
