If we get a breakthrough moment with quantum, the machines will not be evenly distributed to start with. They will be too expensive to build, power and cool unless you’re a fortune 500 exactly like LLMs right now (aside from small models like llama that can run on consumer hardware). At the moment quantum computers rely on superconductors that have to be cooled near absolute zero which is… somewhat expensive to achieve.

Unlike LLMs (oh no I can’t talk to waifu without cell coverage waah) Not being able to run quantum algorithms on your phone in this scenario would be bad. It either means your personal comms are, for all intents and purposes decryptable by those who control the quantum machines or that you’ll have to pay rent to the people who control quantum machines to have them encrypt and decrypt stuff for you. Of course you’ll have to trust them too. Also, given governments thirst for spying on our encrypted comms, it’s possible that quantum machines are heavily regulated allowing “the good guys” a back door into our chats without giving “the baddies” a way to encrypt their comms
