Joshua is more resistant than Kenenisa, at the time Kenenisa ran his WRs. Already two years ago, Cheptegei bettered the WR of 15 km on road (41'05"), something Kenenisa couldn't do in 2004.
Cheptegei always was able to run with the max mental concentration when was alone, and this is one of the most important qualities when we speak about WRs, because athletes with this goal needs, always, run a big part of the race alone.
It's not a risk to see Joshua as new WR holder in 10000m (Kenenisa NEVER really prepared that event, running the 25 laps with the preparation for 5000m), with some possibility to be the first athletes running under 26', and, in 3 years time, as new king of HM well under 58'.
If he will move to Marathon after 2025, he can be the athlete running well under 2 hr in official competition. He's really the new king of long distances, congrats to him, his management (Global) and his coach.
