I feel as though quantum is just starting to get to the point of interesting but is still too early for me to get excited about as having practical application within my career time frame (I expect to be retired in ~15 years).
Leetcode ain't cutting it. If you want to do cool shit, hit the books and learn real engineering. Arizona [0], Rochester [1], UCF (Florida) [2], and CU Boulder [3] are the best distance learning programs in this space, but all expect a deep background in Physics to succeed.
Additionally, most private sector employers in the space remain in the US, Canada, China, and France (but increasingly integrated with the US thanks to the CQE).
