    "Breakthrough Starshot" has the only plan that is feasible and not in direct conflict with known scientific principles.

    Everything else I've ever heard of relies on (let's be charitable) unproven ideas.

    We can't do interstellar travel now and we won't for a very long time.

    Send a machine.

    Machines can handle more G-forces, and don't mind a boring flight that would take a year or longer, with no chance of ever returning

    Using current technology

    solar sails

    take very long time

    If you want to get people there

    you'll need to build a multi-generational colony ship

    exorbitantly expensive

    and good luck getting qualified experts to sign up for the one-way trip

    living a spartan lifestyle for the remainder of their lives

    caged in a ship that neither they nor their children nor their great-great-grandchildren can leave

    (but maybe their great-great-great-great-umpteen-greats grandchildren will find a habitable planet in the target solar system...or maybe not)

      Probably they'd never send a ship until after they'd detected what they believed to be a livable planet...but there's no guarantee that the planet is habitable even if it has considerable oxygen in the atmosphere and liquid water. Radiation, poison substances in the water or soil, etc. might exist

    First we need to ask: "Why to get to exoplanets?".

    I doubt if they will be what they are currently cracked up to be.

    Spaceships we don't have yet.
