What is preventing us from sending numerous tiny probes/orbiters into interstellar space, do we still lack the technology or courage? Since through gravity assist alone we can increase the speed of spacecrafts, why don't we send out many in various directions, with all the necessary instruments, like we've sent to mars?
If not the probes then why not just orbiters? Can we not launch tiny bots or something kinda similar to the breakthrough starshot?
