Nobody's going to the stars, regardless of technology level. They're much too far away, and the incentives are much too weak. Staying on a planet in a nice comfy habitable-zone orbit around a star, is just *overwhelmingly* more convenient, than setting out on a multi-generational voyage to a distant location that probably offers you nothing you don't already have closer to home.
We're going to continue to explore the system we're in, and we're probably going to put telescopes in a few more places (perhaps at a couple of the earth-sun lagrange points, for instance) in an attempt to *see* a bit further out. Maybe we'll even send probes. But actually going ourselves, is a total non-starter. It's fun to write stories about, for entertainment purposes, when you don't have to be realistic. But it's not even remotely practicable.
People underestimate how far away the stars are, and think things like "Oh, if we could go maybe a tenth of light speed, then a trip to the nearest star could be 40 years." But it couldn't, because you're assuming instant acceleration, and nothing can survive that. Spreading the aceleration out means you can't do most of it with the slingshot effect, so it becomes very expensive to achieve. Using thrusters, for example, the amount of reaction mass needed to handle a voyage that long in a comfortable way (acelerate for the first half, then decelerate for the second half) is prohibitive, even if the energy is free. The only *practical* way to do it is with laws-of-physics-optional sci-fi propulsion technology. Hyperspace or warp drive or wormhole generators or space folding tech or some jazz like that. None of which is consistent with what we think we know about physics. So unless we find out that the standard model is very very wrong in some fundamental way, going to the stars is not happening.
