On first glance I thought maybe this was a little step too far in the Gen-Z direction that could alienate older users.

But Google’s product teams say the design system actually enabled older users to spot key interactive elements on the screen just as fast as younger users across 10 apps tested.

Contractors are losing their jobs to Al at DuoLingo.

It's not difficult to see why.

Here's a comparison of the time it took to complete 100 vs 150 courses with and without AI:

Plus, DuoLingo’s CEO jumps on the AI-first bandwagon with a memo published on LinkedIn that unveils how the company plans to implement its own AI policies (it’s not good news for contractors). And the latest release from Mastercard that takes the application of AI agents to the next level.

This is where AI models won’t rely on human data any more; instead, it will physically interact with the real world to generate new insights from the data it generates.

"Ultimately, experiential data will eclipse the scale and quality of human-generated data," Silver and Sutton write.

A new research paper from Google suggests that the “Era of Experience” is upon us.

The researchers suggest that AI has evolved from the simulation era where it played games like chess and the era of human data where it consumed human data for training purposes to now enter the era of experience.

Healthy living, personalised kids stories, image generation and explaining “legalese” are some of the fastest growing generative AI use cases.

It’s becoming strangely essential for tech companies to keep on top of this to understand how AI is cannibalising their value proposition.

UI consistency is important but I wish Notion had done something a little different for their Mail product to ensure it has an identity of its own.

I've been playing around with Notion's new Mail product for the past few weeks.

It's super clean and easy to use but the biggest drawback for me is that it looks and functions far too much like Notion's core product that it's actually a little bit confusing.

The agent uses a tournament-style system, inspired by methods like ELO ranking, to evaluate and rank ideas based on user-defined criteria (e.g., feasibility, originality, or impact). Each idea is analyzed for strengths and weaknesses resulting in a prioritized list from highest to lowest rank.

Once requirements are finalized, the agent employs hundreds of AI sub-agents to produce a large volume of ideas (typically 100–200) in just a few minutes. These ideas are created by exploring diverse perspectives and possibilities within the defined scope.
