Thoughts from John Karahalis
Certainty is impossible. Show me someone who's certain, and I'll show you someone who's underinformed.
Am I guilty of overconfidence in my views? Of course. I think many people are. It's something I'd like to continually, imperfectly correct for, however.
edit (2026-01-27): I later deleted these chatbots. I wrote about the decision to do so in a blog post.
I created some chatbots which pretend to be historical figures. They respond to messages based on the knowledge, values, and personality of the people they represent. To use one, simply click its link and follow the on-screen instructions. None of the money currently goes to me.
I'm sure there will be hiccups, as there always are, but I'm proud of them. I think they'll be especially useful in education. What better way to learn than by talking to the topic of one's studies?
The GPTs are built on top of ChatGPT and will launch with the GPT Store some time this week. To use them, one must sign up for ChatGPT Plus, which currently costs $20/mo. None of that money goes to me, and there's currently no way for me to charge an additional fee to use one of my GPTs. OpenAI may adopt a revenue-sharing model in the future, but it hasn't been rolled out yet. I have opinions on that (“Let's make the marketplace less like the App Store and more like Spotify!” —No publisher ever), but there isn't much I can do about it right now. If I become annoyed enough by the enshittification, I'll consider removing my GPTs in protest. Besides, I don't honestly expect I'll make much money (or any money) doing this. It's just fun.
I have to share credit with my dad, who expressed an interest in chatting with an AI version of Abraham Lincoln. Now it's possible! I'm sure I'll add more historical figures in the future, so keep an eye out. When the GPT store launches, perhaps you'll be able to search my name or otherwise search for GPTs made by me.
Here's another thing I do to make my technology less addictive, in addition to using the Unhook add-on, using focus mode on my phone, using permanent Do Not Disturb on my smartwatch, and using permanent Do Not Disturb on my smartphone:
I use the Clickbait Remover add-on in every browser that supports it. It replaces ridiculous, attention-grabbing YouTube video thumbnails with images that are actually grabbed from the video. In that way, it defeats the dishonest alarmism that creators employ to win your attention. It's one more reason I disable the YouTube app on my phone, using Android's wellness tools to limit the app to 0 minutes per day, and only use YouTube through web browsers, where these add-ons can take effect.
There's another add-on, DeArrow which de-shittifies both thumbnails and titles. I don't use it because I feel it's a little overzealous and because I think its settings UI is overwhelming, a pet peeve, but others might like it. It's made by Ajay Ramachandran, who also made SponsorBlock, which skips over sponsored content in videos.
“You can't connect the dots looking forward, you can only connect them looking backwards… Believing that the dots will connect down the road will give you the confidence to follow your heart even when it leads you off the well-worn path, and that will make all the difference.”
—Steve Jobs in his 2005 Stanford Commencement Address
Don't trust others' plans for you. You'll soon discover they don't have very much planned at all.
I'm not sure where I first heard that advice, but it appears to be derived from a quote which is, accurately or not, attributed to Jim Rohn:
If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much.
I tend to prefer the shorter version, but they both have their strengths. In any case, I think the advice is sound, and I hope to remember it.
Here's another technique I use to keep my devices user-friendly, in addition to using focus mode on my phone, using permanent Do Not Disturb on my smartwatch, and using permanent Do Not Disturb on my smartphone:
I use the Unhook add-on in all browsers to remove all addictive and manipulative features from YouTube's website: recommended videos, trending videos, shorts, autoplay, and even the homepage, which has become a hodgepodge of the others. As I've mentioned before, YouTube is just too good at wasting my time. I've actually disabled the YouTube app on my phone, forcing myself to use their website instead, so that I can always benefit from Unhook. I recommend everyone install it.
Here's another technique I use to make gadgets less manipulative and addictive, in addition to perpetually using Do Not Disturb on my phone and smartwatch:
I use Focus mode on Android during work hours. The feature disables apps of my choosing during the specified time frame. It's actually not quite as helpful as it might seem, largely because Google allows the user to work around it very easily, almost encouraging the user to stop using it, but it's one small piece of a larger puzzle. I'm sure iOS has something similar, and perhaps it's not quite as self-defeating over there.
As part of my ongoing effort to share techniques for making modern devices less addictive and manipulative, here's another trick I use in addition to perpetually using Do Not Disturb on my smartphone:
My smartwatch is always in Do Not Disturb mode. It only makes noise when an alarm or timer goes off, and it never vibrates. There are no other exceptions because Wear OS apparently doesn't allow them. (I wouldn't mind getting a buzz from FitBit when it's time to move, but configuring that does not appear to be possible.)
Some might wonder why I have a smartwatch at all. It's a good question. Aside from knowing the time, I mostly use it to track my sleep. I honestly don't care about most of the other features.
edit (2025-12-14): Some time after writing this blog post, I sold the smartwatch and got a mechanical watch, which I recommend! I track my sleep using another app, and I honestly don't even need to do that. I don't need sleep tracking to know what worsens or improves my sleep.
I can become absorbed by technology like anyone else, but the nature of my absorption sometimes looks different because I work hard to make my gadgets less addictive. Over time, I'd like to share some of the techniques I use. Here's the first one, which I've mentioned before:
My phone is always in Do Not Disturb mode. I don't get any beeps or buzzes, except for emergency alerts, alarms, calendar reminders, phone calls within certain parameters (close contacts, repeat callers, etc.), and Slack messages from colleagues. I almost never need to be immediately alerted about anything else; I check my phone often enough already.
Interestingly, this isn't very easy to configure. Modern devices mostly require that we opt out of distractions, rather than opt in. Put another way, if the mode that respects our attention is called Do Not Disturb, what is the ordinary mode called?
