As someone who was invited to attend - I really wished the talks were more low level and technical. I'd really enjoy talks about how things are implemented in Chrome, how the underlying APIs (for PWAs for example) work and so on.
We need to do a better job at audience segmentation because we have ranges from senior dev to student, and CxO's etc and that's roughly why we stay a tad higher level with a lot of case studies.
We might end up with different days or different events for the audiences.
Because of this, I want to say thank you precisely for not giving more lower-level details in your talks.
If there are multiple tracks on the same day, maybe consider a high and low level track?
The only conference I've been to that felt targeted to me was Django Under The Hood, which is billed as very technical talks about the innards of a framework.
