It's frustrating but unfortunately all-too-common to see the number of posts in this thread subtly (or not-so-subtly) questioning the "seriousness" of the speaker. In my opinion, this talk is doing one of the most important things for Rust in particular and our industry in general: demonstrating that badass technology is not exclusively reserved for the Very Serious People of the world, but that enabling technologies and communities with the right attitude, like Rust, can unlock people's potential and give them opportunities that were otherwise unattainable for them.

Nothing makes me more excited about Rust than its enabling potential, and this talk hits on all the most important themes. (In my own small way, I'm trying to help push on this Rust theme by helping the Rust subcommunity of language bridges, to create better on-ramps for programmers in other ecosystems to make use of Rust.)

I think it behooves all of us, particularly those of us who haven't had to deal with being a member of a class of people whose credentials are constantly questioned, to ask ourselves what unconscious biases may be causing us to doubt the validity of a presentation based on signifiers like "too many doodles" or "I happen not to have known <some specific fact>," instead of addressing the actual content.

But again, I just want to say that I am over the moon that this was the closing talk at RustConf. Rust could have no higher calling than to be an instrument of opportunity for new systems programmers.
