Why does Gulliver find Laputa boring?

Gulliver finds Laputa terribly boring because the people there are all much more intelligent than he is. He has a hard time conversing with them and is generally ignored.He petitions to go down to Balnibarbi, and his request is granted. On Balnibarbi, Gulliver meets Lord Munodi, who invites Gulliver to stay at his home. Munodi's home is beautiful and kept well, but when the two travel out into the country Gulliver finds that the rest of the land is barren and sadly kept. Munodi explains that this is because many years back, people from Balnibarbi visited Laputa, and when they returned they decided to change things to a more academic way of living. This idea has failed. Munodi's land is plentiful because he never changed his way of living.
