Don't be afraid to drive in another lane. Take the opportunity when you see it.
In a previous life, I had a management who told me to, "stay in my lane" and this led to a series of events where I ultimately left. Anybody who tries to keep you down or limit you ability to learn and think needs to be avoided. Those who foster this type of growth need to be held close.
Our industry is prone to the latter. By all means, explore other lanes, but don't be that guy. By all means, learn, but please do this from a place of curiosity and humility.
Ask people who live in that lane how you can grow. Volunteer for the scut work until you deeply understand it. Be a partner to the people who spent a lot of time growing in that lane, not an antagonist. (I'm sure PP is aware of that, I'm using the generic 'you', not the personal)
The English language has a specific word for that: “one” instead of “you”, but sadly this word has become more and more antiquated.
One has to make tradeoffs ;)
Also beware of neglecting to fulfil the responsibilities and expectations of the lane you are ultimately being evaluated in, especially earlier in your career. I've given the (common) advice to junior engineers to become the team expert in one thing relevant to the team (something akin to this was even in the SDE1-2 promotion rubric at Amazon), but occasionally that advice needs tempered by subsequent advice on not tunnel-visioning on that one thing (and/or choosing a more relevant thing).
Broadly agree with the article and the general advice here though!
