Yep, once we learn a better way of getting places than very large firework's. Some promising current tech are things like nuclear electric, we use ion thrusters now, they are super efficient but low thrust for now. A fusion breakthrough would help a lot. But we could realistically get up to 0.2C (1/8 of light speed) but possibly that would be something like nano probes with light sails on a laser high way in a long row of thousands of individual probes and a signal is relayed back along (see Breakthrough starshot) That would reasonably get us closer up data of surrounding solar systems in a reasonable time.
