Aren't we kinda capable of going to another solar system? Multiple generations of travel perhaps, and at an extreme cost. But with technology we have today it could potentially be possible.

So, does that mean they would have to be vastly more advanced than us?

Although it probably is a fairly narrow band of development. That said we have no idea the speed of development another species would be capable of compared to us.

    We are no where near being capable of that.

    Using a laser beam to push a solar sail dragging a mini probe behind it (which is the closest thing as are even relatively close to) is a far far far cry from having the self-sustaining life-support technology to last the centuries it would take to get there.

    The only way a "human" will ever experience a different solar system or galaxy is if we do reach singularity, and decide to copy conscience to programing and send it into space. This tech will eventually exist. Maybe, and way down the line. Space distance is beyond the contemplation of understanding. The thing we launched in 1978 is 1 light DAY from earth. The single closest star is Proxima Centauri and it is 4.25 light years away.

    A computer program version of some future scientist could go into sleep mode for the duration of the flight and wake up in orbit in 71,000 years. (At voyager speed. Will likely be faster once that tech is around.)

    no, thats sci-fi. we would be travelling near relativistic speeds if we want to do that, but we are subject to things like time dilation. this was always a trope in sub-ftl travel(travelling close to speed of light, but the time effects is so wierd. you arnt actually doing the whole 10s of thousands of years in our perspective, but to the passengers, it takes less time.

    also we dont have FTL, thats pure scifi(its almost always involved bypassing the speed of light as to not violate that universal constant, usually its interdiminesional travel. trek has several methods, warp which is just spatial manipulation to move the vessel across space, transwarp/voth/vortex, which is interdimensional travel to by pass the speed of light, most others are using teleportation which is not truel ftl movement, but its considered ftl.
