I love watching Lets Plays and HCBailly is the best let's player. His quality has only gone up over the years and his consistent upload schedule leaves nothing to be desired. He's under rated and deserves 3 million subs.

Summoning Salt.

Not many people can make a 2 hr video about the world record progression of a game I've never heard of and have me absolutely invested in it all the way through.

Dude makes a video every 3-6months but god I love them. If anything they've improved over the years as his style has been refined and the videos got longer.

Makes great visual math videos. Without him I would have never studied electronics.

Technology Connections!

CAPTAIN DISILLUSION

Stumpt. Despite having 540k subs, they aren't one of the super high energy balls to the walls energy where every 5 seconds they zoom in on a small part of the video. They usually have a much more calm energy about them and one thing I really like is how they aren't telling you to like and subscribe every few minutes, let alone at all in their videos usually.

Ze Frank

Seems like he’s been doing his thing for the entire existence of the internet. Silly little flash animations and games in the early 2000’s and now his ‘true facts’ of animals videos. Seems to keep true to his own style, ever evolving as it may be, but always similar- and maybe thats what I find comforting- he’s been there for most of the 20+ years I’ve been ‘surfin the web’, as the kids like to say.

Haven't seen Summoning Salt mentioned yet. He does great videos on the history of speed running a video game.

An example video would be Super Mario Bros: The Human Limit where the difference between a tool assisted speed run and what a human is capable is discussed. And how Super Mario Bros has an interesting mechanic allowing humans to be imperfect but still able to tie a perfectly executed speed run done using essentially a script of commands.

Primitive Technology

He's mastered the bronze age and is making progress on the iron age, all by himself.

Gaming

• EthosLab - most authentic Minecraft YouTuber around. No trash clickbait, cringeworthy attempts to appeal to children, ad spam, etc. Just a dude chilling out and playing Minecraft.

• Battle(non)sense - Tests various input lag reduction tech + strategies. Input Lag: Low DPI vs High DPI - turns out increasing your DPI can significantly reduce input lag! AMD AntiLag+ vs Nvidia Reflex - turns out not only does AMD's solution trigger anti-cheat, but it also offen increases system latency.

• Marblr - High quality analysis of weird game behavior. Mostly Overwatch for now. Overwatch: The Effectiveness of Shield Spinning

• People Make Games - Videos about games and the gaming industry. Highly accessible to folks not familiar with the industry. Making Sense of VR Chat, the Metaverse People Actually Like

• NoClip - Crowd funded feature length video game documentaries. Making of Horizon Zero Dawn

Makers

• ColinFurze - builds crazy stuff and does an amazing job of it! Currently building an underground garage at his house that connects to his underground tunnel system.

• I Did a Thing - Australian man with a great sense of humor. Makes ridiculous stuff. Giant Beyblade destroys stuff

Science + Technology

• Applied Science - In depth videos about random science-y things this dude finds interesting. No clickbait, just an excited dude talking about a project he tried.

• Atomic Frontier - A lot like Tom Scott. He's also a rare case where the video is more interesting than the title/thumbnail. Generally focused on science-y topics + has shockingly high production value considering the dude seems to be an overworked college student.

• NileRed/NileBlue - Crazy in depth chemistry videos. Personally find NileBlue more entertaining as he tends to explore things he's not that great at.

• Practical Engineering - Explanations of various civil engineering concepts.

Other

• Krazam - Legendary comedy channel focused on software engineering related topics. Most famous video - microservices.

• You Suck At Cooking - Short videos presenting recipes in an entertaining way.

• Studio Binder ; High quality videos about all things movie/video production. Owned by a movie production software company so you're gonna see ads for it in every video but SponsorBlock gets rid of that with no issues. Ultimate Guide to Camera Movement - Every Technique Explained

Lemmino creates amazing documentaries about a wide variety of topics (DB Cooper, JFK Assassination, Jack the Ripper). He uploads very infrequently, but it's totally worth it when he does.

Barely Sociable is similar in style and uploads high quality pieces about various mysterious occurrences.

Drachinifel uploads frequent, well researched content about naval history from the age of sail to the 1950s.

Our Own Devices is a very small channel that feels similar to Technology Connections (another excellent channel). He uploads content about the history and inner workings of old devices of all sorts.

Throttle House is the best car channel on YouTube.

Jason Cammisa's Revelations series on the Hagerty channel has really good deep dives into the histories of some important cars.

Aging Wheels/Under Dunn are excellent car and/or wood project channels. Chickens make frequent appearances too.

Mentour Pilot has excellent analysis of airline crashes.

Jay Foreman uploads funny and informative content about maps (Map Men) and tidbits about the history of London.

Cathode Ray Dude uploads deep dives into weird computers, computer peripherals, and old cameras. I've watched his half hour video about modems at least 5 times.

Mustard uploads excellent content about crazy ideas in transportation (like the Soviet love affair with the ekranoplan).

Primative Technology. A dude out in the bush building houses and tools out of mud, sticks, and rocks without speaking a word.
