It doesn't have to be that extreme. Even if rather than "godlike capabilities" it just boosted your economic efficiency by 2x over other nations that would still be a serious geopolitical threat. (I'm not necessarily saying that's a realistic outcome either, but it's certainly more realistic.)

If your enemy has a theoretical non-zero chance of achieving infinite power, does it justify expending near-infinite resources to get there first?

I guess we’ll find out.
