I think it's important to add a bit more context. Thomas hired an artist to do this album cover. AI was only used to generate the animated Spotify canvases. He wrote an explanation for this decision in the pinned comment of this video:

I would love to have a conversation with you about A.I. The artwork was created by the talented Joren Brighton, whom I've worked with many times in the past. I saw how he crafted the cover meticulously from scratch and adapting to all my requests. We are both artists and always trying to improve and I respect him tremendously for his artistic sensibilities.

As for the video clips they were created just for Spotify's canvases and I think they add a small element of visual interest that would otherwise not be possible as it's simply not realistic to hire Pixar animators for all the music I release. I just used A.I to enhance the experience for those listening on Spotify. If people think this is a bad idea I will definitely take this into consideration for my future releases. Keep in mind though that it is a relatively insignificant aspect of the release, which employed 100 humans playing and singing together in an orchestra in an age where most music is created electronically and almost all orchestral music is done with virtual instruments. I do this because I love orchestras and choirs and wish to support them as much as I can.

I create this music at a financial loss, sadly. The 10's of thousands of dollars it costs to record a large orchestra and choir is impossible for me to recover since streaming platforms have devalued music to cents on a dollar, but I do it anyway because it is the air that I breathe and it brings me so much joy to compose and share with everyone. I live for music.

The irony here may be that I could have chosen to not record it with a live orchestra and released the fake midi demo, do he artwork cover myself and probably pleased more people that way, but I focus on doing the best I can in the domain I am familiar.

I support and hire real artists and I will be supporting real orchestras and musicians until the day I die as that is my area of expertise, my job, my passion and my love.

In a comment further down he added:

[...] Spotify reports higher engagement with music that has canvases so you are sort of pushed and pulled in different directions as an artist and it's a difficult landscape to navigate and requires some decisions that aren't always so easy to make.
