Is using Midjourney legal?

Yes, using Midjourney is legal. Midjourney refers to a journey or process that one undertakes, typically implicating metaphorical or literal travel, exploration, projects, careers, or other life experiences. In the context of life's endeavors, "Midjourney" stands for the phase between the commencement and completion of any given task or experience. As such, there is no legal impediment to being in or acknowledging a mid-journey state within any lawful undertaking. Moreover, if Midjourney refers to a specific service, product, program, or tool that has been lawfully created and distributed, using it would also be legal as long as one abides by any terms of service, licensing agreements, or other regulations pertinent to its use.
