There is no answer that fits everyone. I wouldn't try to take the hands off from the technology - Elon Must is still the key engineer at his companies. Instead trying to build yourself as an executive, try demonstrating more leadership skills to your peers and superiors. If you hear a good feedback from your surroundings (give it a few months), it may be a good opportunity to talk to your manager. Additionally, it is always good to look for mentors. Find someone you appreciate and ask it. You will be surprised how much extraordinary executives will be happy to assist you.
