I feel like something is wrong where you are, maybe your juniors do not feel incentivized or encouraged to learn, code reviews might not be strict enough, quality may not be valued enough, and immense pressure to move tickets might be put on people, or all of the above in various doses.

I feel this way because at my company our interns on a gap year from their comp sci degree don't blame the compiler, cosmic bits, or blindly copy from stack overflow.

They're incentivized and encouraged to learn and absolutely choose to do so. The same goes for seniors.

If you say 'I've been learning about X for ticket Y' in the standup people basically applaud it, managers like us training ourselves to be better.

Sure managers may want to see a brief summary or a write-up applicable to our department if you aren't putting code down for a few days, but that's the only friction.
