Happy Wednesday 👋 and a warm welcome to Tech Talks Weekly #100!

It’s pretty incredible we’re hitting the 100th issue this week!

When I started Tech Talks Weekly two years ago, this was just an experiment. My intention was to simply share great talks I’d watch myself with a small audience of passionate folks. Nothing changed besides that this audience is now pretty huge. Tech Talks Weekly is likely to exceed 10,000 readers in a month or two, which is absolutely amazing.

Thank you for being part of this journey 🙏

Let’s now jump straight into the talks!
