CUSTOMERS ARE JUMPING FROM CHATBOTS TO CHECKOUT. IS YOUR SITE READY?
(SPONSOR) [4]

AI is compressing the customer journey. Customers used to discover,
evaluate, and select products on your site. Now they're chatting with
a bot and going straight to checkout.

Rokt's latest whitepaper [4] is based on data from billions of
transactions. It covers:

* How checkout is taking on new strategic work
* Understanding the economics and customer mindset in each step: Selection, Cart, Payment, Confirmation
* Why the same offer can create value on one step and destroy it on another.
* The relevance infrastructure [4] that helps brands stand out

ANTHROPIC DEBUTS CLAUDE DESIGN FOR CREATING PROTOTYPES, PITCH DECKS,
AND MOCKUPS (2 MINUTE READ) [5]

Claude Design can create designs, prototypes, slides, and more using
Opus 4.7, an AI model that was introduced earlier this week. It can
see images in greater resolution than Anthropic's previous models and
is more 'tasteful and creative' when performing professional tasks.
Claude Design allows founders, product managers, and marketers without
a design background to create high-quality interfaces, slides, and
docs. Teams in testing have been using it to create realistic
prototypes, wireframes, mock-ups, design explorations, pitch decks, presentations, and social media assets. It is now available as a
research preview for Claude Pro, Max, Team, and Enterprise customers.

APPLE'S REVAMPED SIRI INTERFACE IN IOS 27 IS HIDDEN IN WWDC TEASER (8
MINUTE READ) [6]

Apple's WWDC 2026 teaser provided a glimpse of the revamped Siri
interface that will be part of iOS 27. The teaser hints at a complete
overhaul of Siri that includes previously announced features along
with several additional enhancements. The enhanced Siri will be able
to handle multiple commands within a single query and support
third-party AI agents. The design is still being tested within the
company. The Siri announcement will be a central part of the
announcements at the upcoming WWDC.

BLUE ORIGIN SUCCESSFULLY RE-USES A NEW GLENN ROCKET FOR THE FIRST
TIME EVER (3 MINUTE READ) [7]

Blue Origin successfully reused one of its New Glenn rockets, but the
overall success of the mission is in question as the communications
satellite that the rocket carried to space wound up in an off-nominal
orbit. The company missed its target, which suggests something may
have gone wrong with the rocket's upper stage. It is unclear whether
the upper stage performed its second burn, scheduled an hour after the
rocket lifted off. The re-use feat was achieved on just the third-ever
launch of New Glenn.

PANCREATIC CANCER MRNA VACCINE SHOWS LASTING RESULTS IN AN EARLY
TRIAL (8 MINUTE READ) [8]

mRNA vaccines, personalized for each individual using genetic
material taken from their unique tumor cells, are showing promise in
the fight against pancreatic cancer. These vaccines work as a type of immunotherapy that stamps out lingering, undetected cancer cells after
surgery to remove larger tumors. Traditional immunotherapies only work
in about 20% of all cancers, and pancreatic cancer is the poster child
for difficult-to-treat cancers. The drugmakers behind the vaccine have
now started Phase 2 clinical trials.

instead. [9]

THE AGENT STACK BET (8 MINUTE READ) [10]

Most 'production agents' shipping today feature custom plumbing,
fragile session logic, shared service accounts, and weak security
models. While models and tools have gotten dramatically better, there
is a stack ceiling that is quietly creating a governance and
reliability gap that agentic systems can't grow through. The current
stack has excessive agency, with agents leaving a trail of corrupted
state behind them. This article suggests four architectural bets teams
should consider to move to the next generation of agentic systems.

OUTPUT ISN'T DESIGN (2 MINUTE READ) [11]

Many people mistake design as the act of producing something.
However, the hard part of design is actually understanding the problem
enough to know what and how something should exist at all. There is
use and place for tools, but the tools aren't part of the design
process. Design is the search for a good fit between a form and its
context. Good design considers human needs, technical constraints,
conflicting requirements, habits, edge cases, and easy-to-miss
relationships that require time to identify.

INSIDE NOTION (53 MINUTE READ) [12]

Notion is a company built on ideology, brand, and community rather
than technical edge. The company's software gives users blank pages
they can customize with modular blocks into whatever they want. Notion
became the canonical product-led growth company after it first took
off in 2018, propelled by brand ambassadors, influencers, and fandoms
across social media. This article explores how the company works and
how it became one of the top 10 most-used AI products in the world,
despite not being 'AI-native'.

META TARGETS 20 MAY FOR 8,000 LAYOFFS AS IT REDIRECTS BILLIONS TOWARD
AI INFRASTRUCTURE (9 MINUTE READ) [13]

Meta plans to cut approximately 10% of its workforce starting on May
20. The layoffs will hit teams across Reality Labs, the Facebook
social division, recruiting, sales, and global operations. The
restructure is being driven by a reallocation toward AI infrastructure spending. Teams will be reorganized into AI-focused 'pods' under Superintelligence Labs.
