There’s so much to learn out there and only so few hours in the day…
Not only that I feel like my own space of ideas for projects is limited by my own interests, what I know, and what I come across.
I think a good way to expand my world would be to hear what projects people would love to work on…if only they had the time. Would love to hear from @trust_level_1 on this
Oh man, where to start 
If I had the time, I would definitely love to work on developing a 3D-Pose estimation model. This could be used as a relatively low-cost motion capture system - so you could animate video game characters without having to invest in expensive motion capture hardware/software. Not to mention the applications in rehabilitation monitoring for athletes/patients.
Current 2D pose estimation models are good, but there are still issues with occluded joints, which leads to inaccurate/noisy results when the body is in certain positions.
As a workaround, I’ve had a project in the back burner where I was thinking of using 2 camera inputs - each being processed by a 2D pose estimation algorithm - and then trying to triangulate the 3D pose using trigonometry. Maybe one day 
That’s one of the biggest trends I picked up on at the ECCV conference: pose estimation.
There was a lot of posters presented on that topic.
Here are a couple from there:
