AI is forcing us to pay off 40 years of technical debt

If you have a personal Google AI subscription, all your saved chat history in Gemini can be used for training and there is no way to opt out unless you turn off chat history or use temporary chat sessions. These chat transcripts may even be read by human reviewers. Although Google claims to disconnect them from your account when human-reviewed, they explicitly warn not to enter confidential information.https:&#x2F;&#x2F;support.google.com&#x2F;gemini&#x2F;answer&#x2F;16836988“[Gemini app activity] is used to improve Google services for everyone, including by training generative AI models, if your Keep Activity setting is on.“https:&#x2F;&#x2F;support.google.com&#x2F;gemini&#x2F;answer&#x2F;13594961?hl=en#human_review“A subset of chats are reviewed by human reviewers”https:&#x2F;&#x2F;support.google.com&#x2F;gemini&#x2F;answer&#x2F;13594961?hl=en#pn_retain_data“Chats reviewed by human reviewers [...] are not deleted when you delete your activity. Instead, they are retained for up to three years.”https:&#x2F;&#x2F;support.google.com&#x2F;gemini&#x2F;answer&#x2F;13594961?hl=en#pn_data_usage“Please don’t enter confidential information that you wouldn’t want a reviewer to see or Google to use to improve our services, including machine-learning technologies.”To disable their training on your chat sessions, you need to turn off “Keep Activity” in Gemini’s settings. Turning that off means you’ll lose any chat sessions after 72 hours.I learned this too late, thinking that having a paid subscription = not being turned into the product. Apparently paying is not enough.Thank you to this user on HN for mentioning in another thread: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=50355424

Nvidia RTX Spark encrypted firmware slows inference speed to 35% on Linux

I saw HackerTube (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=50319510">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=50319510</a>) a few days ago, the YouTube videos HN keeps
recommending, pulled from 19 years of comments. It made me want to flip
through them instead of picking, so I built a TV for it. I have Algo fatigue.Each topic area is a channel (DEVTV, SOLDER, RETRO, ORBIT, ...), plus HN Prime
(the top 400), a music channel, and Late Night on ch 99, which only broadcasts
11pm-5am your local time and shows color bars otherwise.Similar to HackerTube it was built with Claude Code in a few hours.All credit for the data goes to HackerTube. Happy to hear channel ideas.

To give you some context on the project. I&#x27;m a solo founder and I use AI heavily in my work. The idea came from wanting players to discover cities. Each city has its own history, so every case is set in a real city with real public places. The crime and the people are on other hand invented. The part that I care most is the playable aspect of the game, a model plays the detective and must solve the case before it goes live.As of today: it&#x27;s free on Android, the iOS version is still waiting to be reviewed by Apple. It&#x27;s available in six popular languages, but adding more languages is just a matter of time and demand.My long term vision if it takes off: weekly cases, private parties like a team-building escape game, an MCP so a game master can build their own scenario from ChatGPT or Claude, and maybe tourism offices since players travel the world.
