Why I'm Starting This Blog

A lifelong generalist, a backlog of half-finished ideas, and why AI finally ties them all together.

Welcome to my blog.

I haven't had a website in a long time. I've been busy building and scaling developer ecosystems across IoT, edge computing, API management, semiconductors, edge AI, AI, and decentralized infrastructure. I eventually reached the point where I had so many projects and ideas that I needed one place to organize them. With how fast AI is moving, it's now easier than ever for me to build that place, fill it with the work I've done over the years, and share what I'm working on now.

I'm extremely excited about AI. As a lifelong technologist, technical evangelist, and ecosystem builder, I feel like I've been handed Thor's hammer. For the first time, I can explore, track, save, iterate on, and improve all of my ideas at once, in one place.

This site has become the hub for all of it: projects like Lineage, my portfolio of past products (including my mobile apps and games), the hackathons, workshops, roadshows, and developer programs I've built over the years, and the AI agent projects I seem to be starting every day.

There's plenty to be concerned about. AI is quickly opening up fields that used to belong only to deep subject-matter experts. It feels like everything has suddenly been cracked open. Whatever you can imagine, you can increasingly build.

For people like me, who dreamed up a lot of things and set them aside over the years, that changes everything. I've been going back through my backlog of old blog posts and wishful thinking and realizing it's all possible now. If anything, I wasn't ambitious enough. Want to build low-cost, 3D-printed humanoid robots? You can. Generate a two-hour movie? You can. Release a music album? You can. Build a website that hosts a dozen projects, work on all of them at once, and have a second brain powered by Grok Bot that tracks everything and nudges you when you forget what you should be doing? You can do that too. So that's what I'm doing.

I'm not sure anyone will read this, but for me it's a revelation. For most of my career, as a hyper-generalist who works in technology because I love it, I've felt like part of a small minority. Plenty of people are in tech because it pays. I'm here because I love it. I love talking to the most innovative people, learning from them, and turning their ideas into projects like the ones on this site. I hope to meet many more of them.

In Akira Kurosawa's Ran, an aging warlord gathers his three sons and shows them that a single arrow snaps easily, but three bound together cannot be broken. I think AI does the same thing for generalists like me. All the scattered ideas and half-finished projects can finally be bundled together: tracked, managed, developed, and refined in one place.

I've come to realize that all those failed projects and abandoned or forgotten ideas were actually seeds of what would come next. I have years of blog posts, half-formed ideas, emails, and slide decks I never followed through on. Now I can hand them to AI, work on them together, incubate them as subdomains on this site, and spin them out one at a time. That's exactly what I'm doing.

I'm narrating this post into Grok Bot while driving to San Francisco, and I'm more enthusiastic than I've been at any point in my career. The fear of AI displacing jobs and upending careers is real, and it can't be avoided. But when I look out the other side of the window, I see an endless field of possibility opening up.

If you want to see where I take it, this blog is where I'll organize my thinking. It already has a second brain built in to keep me on track. Let's see where this goes, together.
