Kurt J. Mac had better speed up if he wants to keep in the lead of farthest person from spawn. Regarding something I posted about 20 minutes ago, I have decided to start up one of my series from my old youtube channel. It is called "Journey to the Edge of the World", and if I remember correctly, last time, I got to 100,000 blocks in 2 weeks.
They could have reached the Far Lands years ago if they played like I do; I've actually walked farther (distance walked, not distance from spawn, which has never been much more than 3000 blocks) in one world and reached this milestone in less than two years of daily playing:
These are the current stats for the same world - nearly halfway to the current edge of the world/world border:
In the best case (nonstop walking) it would take about 33.78 days to walk to the Far Lands, or 80.75 days to reach the current world border (which could be reached sooner with methods like Elytra, although you'd need some way to quickly top off their durability and craft fireworks to minimize the time).
Of course, they would have to upload a 3 1/2 hour long video every day if they played as I do, though they do upload half hour long videos nearly daily, but mostly for other games (there are not many YouTubers who exclusively upload Minecraft content, especially for the amount of time I've played), and they could also probably travel faster than I do (I've walked/sprinted/sneaked (all one stat in 1.6.4) at about a third of walking speed, plus some additional distance by boat and other methods; minecarts should not count since they need established infrastructure).
I don't really think Kurt is trying to race to the farlands.
JL2579 did a charity livestream riding a minecart to the edge of the Minecraft world from the center out to 30,000,000 blocks. He used a snapshot with faster minecart speed and it took something like 17 days.
