(Since I have given up on punching the time card and only work on AI Blue Dot, this section is a replacement for the more standard list of accomplishments one sees on a CV page. Very informal stuff, but more appropriate at this time.)
Can you say a bit more about your current work?
Working on the AI Blue Dot website has been a surprising adventure. I thought I would just dump my thoughts about AI and be done. But I have learned how important writing is, and how important it is to know exactly who you are writing for. After a lifetime of strictly technical work, I am discovering the pleasure of saying technical things to a general audience. And I indulge, I include some music videos, use a more flowery language when I feel like it, and so on. I want the reader to have some fun while sifting through material which I consider very important for our collective future.
Exactly what audience are you writing for in AI Blue Dot?
The language I use and the concepts I present are aimed at a most general audience. On one hand, I have removed some more technical material which assumed some exposure to mathematics. On the other hand, when I toned down the technical level too much, it started to sound hollow and unconvincing. So I am continuously refining the articles, trying to find the right balance. Specialists might be disappointed that I use a flowery language sometimes, and that I even venture into poetry and humor. But again, my hope is to keep as large an audience as possible and make it more fun for them.
Would you be interested in leading a new AI venture?
Not in the foreseeable future. I am very appreciative of the emails and social media messages asking me that question, but I have truly paid my dues. The software is still working fine, but the hardware is getting a bit rusty after all that rain. These days doing AI means (because of the dearth of talent) that the team may be spread over many time zones and it may work around the clock. You may have to video-conference at all hours of the day, not the grandfather type of schedule. Now, if my body's epigenetic clock gets somehow reversed, as more people believe it is possible, well ... then maybe ☺ 🏃.
What are some of the lessons you learned in your career?
Perhaps the most important lesson is that you can make many compromises in a project, but you cannot compromise on conceptual integrity. This is true for all large software projects, but guarding the conceptual integrity is particularly important in an AI project because of the increased complexity. Every stakeholder should be able to articulate the goal of the project in a minimal set of sentences. And they should have the confidence that those goals are being pursued. This does not mean the goals cannot change, and they usually do. It only means that whatever they have become, they should be clear to all.
Big AI projects (or any other software projects) are still about people, and less about science or technology. You cannot skimp on the quality of the people you have alongside you, everything will look simpler if you hire the best. Do not be afraid to hire people who are smarter than you are or have superior knowledge. Your combination of technical know-how and leadership skills will not be threatened.
Corporate politics are inevitable. If you can't stomach all the elbowing, it is going to be tough. Don't do it, but be aware of it. Be honest and share your thoughts with all stakeholders, all executives, the investors. Truly try to empower all the people who work with you, and be kind in that process. Being excessively selfish may work short-term for some, but it does not hold long term.
Data Scientists or Machine Learning Engineers?
AI is a young discipline, full of unknowns and misunderstandings. A big problem is finding talent and building a strong core team. There is a clear distinction between the skills of data scientists and those of machine learning (ML) engineers. Both are needed and it is extraordinarily difficult, almost impossible, to find people who can be both. More recent MS and PhD programs at leading universities are working to fill this need.
Data scientists know how to analyze data and usually have PhDs in statistics or in the domain most needed in the project: biology, economics, psychology, etc. The data under analysis is usually distributed over many servers, and moving it around, cleaning it up, and processing it, requires the skill of ML engineers. These engineers are trained in Big Data techniques and use distributed computing platforms like Spark on which to run the ML algorithms. Building teams in which these two separate skills have to be meshed up is a challenge that should not be underestimated. Expect a lot of trial and error.
Dreams and future plans?
I have two whole sections about my love of landscaping and traveling. So I dream of combining the two, and of finding a place (Montana, British Columbia, New Zealand, Argentina, Chile, Malta, etc.), in a naturally stunning setting, and do ALL the landscaping. Like a blank canvas. Build a log cabin, maybe without electricity. Water is needed though, you can't paint with plants and sculpt with trees if you don't have easily available water.
You seem to be leaving out the most important stuff
Well, as I mentioned above, this should be a short business FAQ, but you are right, let me fix that now that you mentioned it. It's a bit cliché, but my big accomplishment has indeed been my family. The kids have grown up to be wonderful adults and now have children of their own. I wanted them to do well in school, but did not push them in any particular direction. Allowed them to experience various systems of thought and go to whatever place of spiritual nourishment they chose. We camped and we hiked and we did some gardening; I wanted them to find the simple pleasures nature has for us. When asked what I thought about their romantic partners, I refused to give either a thumbs up or a thumbs down. That was just too important a choice to make and I did not want to sway them in any which way.
Yes, don't forget to brush your teeth tonight. Not because of its health benefits, but because it wraps up your daily routine with discipline and purpose. (As a bonus, if someone sleeps on the other side of the bed, they will be appreciative. And that may have unpredictable outcomes.)
