    The best free AI courses and certificates in 2025

    I’ve been working with AI for a very long time. I conducted one of the first-ever academic studies of AI ethics as a thesis project way back in the day. I created and launched an expert system development environment before the first link was connected on the World Wide Web. I did some of the first research of AI on RISC-based computing architectures (the chips in your phone) when RISC processors were the size of refrigerators. I also wrote and deployed the AI Editor, a generative AI tool that built news and content dynamically. That may not seem like much today, but I did it way back in 2010, when I had to create a generative AI engine from scratch. At that point, to work, it had to be distributed across five individual servers, each running one agent of a team of clustered AI agents.Also: Six skills you need to become an AI prompt engineerI also have a master’s degree in education, focusing on learning and technology. My specialty is adult online learning, so this kind of stuff is right up my alley. When it comes to the courses and programs I’m spotlighting here, there’s no way I could take all of them. But I have taken at least one course from each vendor, in order to test them out and report back to you. And, given my long background in the world of AI, this is a topic that has fascinated and enthralled me for most of my academic and professional career.With all that, I will say that the absolute high point was when I could get an AI to talk like a pirate.

    Tired of traditional social media? Here are 4 reasons why Substack is my go-to social media app

    ZDNETEvery morning, the first thing I do is grab my phone to turn off the alarm and browse various social media platforms. I usually look through Twitter/X first, bookmarking the articles I want to read throughout the day and seeing what’s happening in pop culture. Then, I go to Instagram and scroll through mutual reels. Sometimes, I check out Reddit for news-gathering purposes.However, I noticed my routine had changed a few days ago. The first app I open now is Substack. Also: Can Digg’s return fix what ails social media today? Reddit’s cofounder is betting on itI’ve been testing Substack for the last couple of months for some personal projects, and I also wanted to keep up with my close friends’ and relatives’ newsletters. Initially, I found it hard to treat Substack like any other social media platform.  Originally a platform used by independent writers to share their work with the opportunity to acquire a following and/or paid subscribers, Substack has expanded. Now, all sorts of content creators — writers, influencers, researchers, historians, fashion and lifestyle bloggers, and more — are using the app to share stories, research, analysis, recipes, and news and cultivate internet communities in a refreshing way. Here are four reasons why Substack is now the first social media app I lean towards to begin my day:  1. Diverse perspectives and content typesOver the last few years, Substack has attracted thousands of independent writers, journalists, and creators by allowing them to monetize their content through paid newsletters. Substack has also become a place of refuge for news professionals burned by legacy media sites and for alternative media publications like former MSNBC commentators Mehdi Hasan’s Zeteo and Joy-Ann Reid’s Joy’s House, independent news outlet Drop Site News, and former WashPo journalist Taylor Lorenz’s User Mag.Also: Can Substack lure creators with its new $20 million program? Here’s how it plans to do itMore recently, I’ve gravitated to Substack for news, personal essays, cultural criticism, and even historical analysis. Opening my Substack inbox every morning to a well-curated selection of writings and choosing something to read or skim to start my day has been a nice alternative to opening Twitter and being accosted with weird political ads, misinformation, and bots.  While gathering a following may take some time, I recommend downloading the app just for the newsletters alone. Substack has also introduced long- and short-form video posts. If reading is not your thing, I’ve also enjoyed listening to video posts ranging from people’s everyday musings to actual news and interviews. Also, with Substack Live, creators can host live videos and bring on guests to have in-depth discussions or gossip sessions you might find on TikTok. 2. It’s more expansiveSubstack is expansive, and I genuinely believe there is something for everyone on the site. There are dedicated sections for culture, technology, fashion, lifestyle, business, politics, food and art, faith, and more. Sorting through it all can be overwhelming, but it only works if you can find and follow the people and content that interest you the most.  Also: I tried replacing Twitter with Bluesky, Threads, and Mastodon: Here’s what I foundUnfortunately, that might take some work on your end. I recommend first following your friends and seeing the type of content they’re interacting with. Then, search for your favorite content creators from other social media platforms to see if they have Substacks. 3. The chat feature The chat feature allows content creators to interact with their communities and encourages their followers to interact with each other in civilized and fun ways. As someone who is interested in internet communities but has also witnessed some toxic behaviors from certain siloed groups on Twitter and TikTok, it is refreshing to see people engage with each other civilly.
