Considering how fast technology should be advancing, he would be obsolete five times over.
Ah, but you're comparing the SW Universe to our universe. It's a little different.
For example, in the Knights of the Old Republic game that literally takes place 4,000 years before the events of the first movie, pretty much everything is still the same. Lightsabers are around, all the technology and starships seem about the same. So if we're to take that at face value, that's 4k years with little to no technological advances at all. That game was hailed as a masterpiece.
Also, remember that the people in the Star Wars universe are not
human. At least, they didn't come from our species, and thus may have significantly different characteristics.
