SRE at 53 watching my role get automated – how do I build something of my own?

I'm a Site Reliability Engineer at a large SaaS company. I can see the writing on the wall as we actively train AI to replace what I do. I'm not interested in retraining for another role that faces the same fate in a few years. I'd rather use this as a forcing function to build something independent. I've been experimenting with AI tools but don't have a clear direction yet. Has anyone successfully made this kind of transition? Looking for honest resources and hard won lessons not highlight reels.
