Be ready to be here for quite some time

Note the following article dealing with space travel. The key point I take away from the article is that we are never getting out of our solar system. No technology works to give rapid travel and without rapid travel, humans would have to go into space for hundreds if not thousands of years in an outdated spaceships with no hope of ever getting new equipment. That's the biggest downside to conventional travel to far away places, in my opinion - no way to get the latest technology to the travelers. Imagine if the Apollo program was actually to go to some far away planet. They would still be in the middle of nowhere while look how the technology progressed in the last 40 years. They would have to basically make do with technology that now is beat by any run of the mill graphic calculator. Same applies to any ship leaving now. Advances are so rapid, and space travel is so slow that even if someone decided to dedicate their entire lives to it, they would basically be stuck techonologically unless they themselves develop something new (which given the limitations of being in a ship with limited resources is virtually impossible). Any thoughts?
