To sum it up, Goku was like "Bye everyone, I am going to spend who knows how many years training Uub and I'll visit from time to time! See yah!"
I get the meaning of it, Goku wanting an earthling to take his place and with all the potential Uub had it seemed like he was his successor, but there are so many aspects that make it idiotic.
1. Goku and Vegeta were still around, with no signs of being unable to take on any threats
2. Gohan, Trunks, and Goten were perfectly able bodied to be trained even before Uub (and well they are half "earthling" and actually born on the planet)
3. There were no potential threats, with it even being the longest period of peace since DB started.
The way that Goku went all in on Uub (when lets face it, he didn't have to live with him) and what felt like him abandoning everyone else, including his granddaughter Pan who was only a toddler, just felt like a misfire for a meaningful end to the series. It felt like a solution in search of a problem since everyone was still around and there was a new generation of fighters (hell even Pan was on her way to being one) already there.
