There are dozens of escalating, yet fundamentally less destructive means to prevent a data centers from continuing to operate (if that's the goal). Not starting at those more modest interventions is political malpractice and in opposition to your harm reduction narrative.
Your P(doom) 'probability estimates' are almost certainly based on unbounded exponential growth curves.
Nature abhors such things; I don't make any plans around their existence, and you shouldn't either. Limiting factors always emerge and dominate the curve, tamping it to a logistic at most.
Get involved with real politics by organizing with other human beings that share your values (posting alone and doomsaying is not praxis), or step back from tech and cherish the limited time you have with the people you love.
