Amen here, as well.

I've spent the last 17 years working for (and now running) tech startups in Boston; the worst of them ceded all fun to cube farms, but the best of them never went all-in on the culture described here. Perhaps there is an east/west coast division here?

I look at the folks working alongside me now, building an incredibly sophisticated machine learning engine for cybersecurity, and I wouldn't think to draw upon a Lego metaphor for what they're doing. It's hard, substantive, mathematical work, and certainly not akin to playing with toys. I expect my senior engineers, sales guys, and marketers to be both protective of the brand we're building and understanding of the need to grow fast and expand our teams.
