His updates came after United States and Thai officials confirmed Sunday that four boys had been rescued from a flooded cave network after spending 15 days trapped along with their soccer team and coach.
Rescuers have been pumping water out of the cave with the goal of letting the boys walk out, rather than having to scuba dive.
The trapped boys could be forced to undertake a perilous escape attempt underwater because a torrent of floodwater is now imminent due to heavy rain. One option to get them out of the cave is to teach them to dive and swim out of the cave. Overnight it emerged that a former Thai navy diver had died while returning from delivering oxygen to the 12 boys and their football coach trapped in the Tham Luang cave complex in Northern Thailand. Mr Musk, who is the co-founder, chairman, product architect and chief executive of Tesla, declared that the firm was finally "a real vehicle company" after reaching the goal.
Rescuers have dug more than 100 holes, hoping to reach the cave by a direct route. Since the Boring Company is all about boring holes underground it makes sense to send them and their ground penetrating radar to Thailand to find a possible spot to begin tunneling to the trapped youths. They were found alive in a flooded cave on July 2, about 2.5 miles from the cave's entrance.

Democrats are voicing alarm about what the new justice could mean for charged issues such as abortion rights and gay rights. Susan Collins, a key Republican vote, was also invited to the White House but is not going, she said Monday.
While the oxygen level had stabilised, he warned levels of "carbon dioxide are another factor" in considering when to move the group - in addition to impending rains which could cover much of the muddy ledge on which the group are sheltering.
Mr Narongsak said discussions regarding the lowest risk rescue attempts were ongoing, but acknowledged that time was against them. The tubes and pods are being built in the United States, a spokesman said.
It is still not clear how the boys will be rescued. It is particularly urgent to get the team out of the cave soon as monsoon rains are expected in the area over the weekend, which would make getting them out almost impossible after the fact.
Officials had initially considered leaving the boys in the chamber to wait out the rainy season - which could have seen them trapped there for up to four months.
