Am i making a mistake by wanting to switch from architecture to backend programming as a junior

I posted on this forum about 2 months ago as I've been having a tough time in the team im in. Im on a 2 year graduate programme in the UK - not an internship but also not a permanent job. At the end of the year i will have to apply for roles internally.

My current role is architectural - I personally have not been enjoying it. I'm working a lot on AI integration, but I feel like you need years of experience to understand architecture to be able to really contribute. I have sort of fought to join another team in the company, as a backend developer where they should hopefully be training me up. Most of the SE at the company are offshores so it's unlikely I will get a return offer as a dev, but I also don't see myself wanting to work as an architect in this team.

My manager keeps telling me that AI is going to come for my job. I don't know if I'm shooting myself in the foot by making this move, but personally I feel that architecture is something you move into years later. I haven't had much experience as an actual SE and I would really like to. I am also still working in this team as an 'architect' so I can still gain some experience there.
