On his videos, Sergey appears fresh-faced and smiling enthusiastically. Speaking in Russian and sometimes in slightly broken English, he goes through coding challenges step-by-step.

His YouTube channel has more than 3,500 subscribers, interested in learning programming languages Python and Unity, or who want to hear more about neural networks, which underlie many artificial intelligence tools.

Mr Mandik said Sergey showed not only remarkable developer skills but also “equally unique” skills in teaching.

“For me, he is kind of a Mozart.”

“I’m absolutely sure that when he reaches 14, he’ll be a guru of teaching and a guru of developing, and that is why we’re really looking forward to this time,” he said.

Not just coders, but salesmen, accountants and others at Moscow-based Pro32 could learn from Sergey, Mr Mandik said.

No promises have been made over pay, as yet, given that the going rate is likely to change significantly.

“We have to wait for seven years,” Mr Mandik said. “Then we will definitely start a conversation about his salary.”
