I could not take the book seriously due to how shallow it was. Written to sound clever, but lacking any actual substance. It literally could have been 2 pages of bullet points and delivered more value by dropping the pseudoscience nonsense and excessive "[famous name] is productive because they do X" trope.
The only takeaway I got was that Deep Work is a bullshit term for having focus.
I thought it was the perfect level of depth, contrast this with something like "Art of Impossible" which spends paragraphs talking about your biochemistry and how it impacts motivation, focus, etc- I couldn't get through it because I don't care about biochemistry, I just want actionable advice with concrete examples from high performers so I can think about how and if I want to apply the advice to my life.
