The real story behind @Careem Quik.

Four years ago, I resisted the idea of opening dark stores and warehouses. The logic was simple: we are a tech company, what business do we have operating physical infrastructure?

But the team convinced me that to provide a dependable customer experience, we had to go deep. We had to control the underlying infrastructure to ensure (i) item availability (especially post-ordering), (ii) quality of fresh produce, and (iii) consistently fast deliveries.

Fast forward to today. @Careem Quik is the fastest-growing quick grocery service in the UAE. We deliver to most of Dubai and Abu Dhabi in 15 minutes, backed by a money-back satisfaction guarantee.

The last five weeks, however, have been the real test. The team has faced more than their fair share of disruptions, yet they have come through every single time to ensure the community is served without interruption. I visited one of our warehouses last week specifically to thank them.

Similar to captains, they are the other frontline that is keeping our cities normal. 🇦🇪

Wharton researchers gave nearly 1,000 high school math students access to ChatGPT during practice problems

Result: chatGPT is the perfect trap.

Look at the red bars.

Students with ChatGPT crushed their practice sessions.

The basic ChatGPT group solved more problems and those on the "tutor" version did even more.

Now look at the gray bars. That's the exam.

No AI allowed.

The ChatGPT group scored 17% worse than kids who practiced with zero technology.

And the fancy tutor version?
No better than working alone.

The researchers called AI a "crutch."

When they analyzed what students actually typed into ChatGPT, most of them just wrote - “What’s the answer?”

The kicker: students who used ChatGPT believed it hadn't hurt their learning.

They were confidently wrong.

This is the AI trap in education.

Outsourcing your thinking.

Of course, lots of half-baked AI literacy curricula being rolled out in schools now

Let’s of course ignore that basic literacy (the ability to read) is possible for <50% of 8th graders

UAE Retains Its Right to Self-Defense

The United Arab Emirates reaffirms that it has not taken any decision to alter its defensive posture in response to the repeated Iranian attacks. The UAE has been subjected to more than one thousand attacks- a number exceeding the total faced by all other targeted countries combined- all of which were intercepted and neutralized by the UAE Armed Forces with the utmost professionalism, efficiency, and distinction.

The UAE reiterates that it is not a party to this war and has not permitted the use of its territory, territorial waters, or airspace for any attack against Iran, consistent with its long-standing policy of good neighborliness, de-escalation, and its firm commitment to the Charter of the United Nations.

Furthermore, the UAE underscores that it retains its legitimate right to self-defense, as recognized under international law and the Charter of the United Nations. The UAE further stresses the importance of journalistic responsibility and the need to rely on official, credible sources before publishing or circulating inaccurate or misleading reports.

Statement by the UAE Ministry of Foreign Affairs in Response to Inaccurate Reporting by Bloomberg

The Ministry of Foreign Affairs categorically rejects the false and misleading claims published by Bloomberg regarding the United Arab Emirates’ advanced defensive capabilities. These assertions are unfounded and misrepresent the UAE’s high level of preparedness, technological sophistication, and operational readiness. The Ministry underscores the importance of responsible journalism and the need to verify information with official sources before publishing inaccurate reports.

The UAE possesses diverse, integrated, and multi-layered air defense systems capable of countering a full spectrum of aerial threats with high efficiency. These long-, medium-, and short-range systems provide comprehensive protection of the nation’s airspace.

The UAE also maintains a robust strategic stockpile of munitions, ensuring sustained interception and response capabilities over extended periods, while preserving full operational readiness to safeguard national security and sovereignty.

The Ministry reaffirms that the UAE’s advanced defense capabilities, institutional readiness, and integrated national security framework remain steadfast and uncompromised. The safety and security of its citizens, residents, and visitors will always remain an absolute priority.

الدفاعات الجوية الإماراتية تتعامل مع 137 صاروخاً و209 طائرة مسيرة

أعلنت وزارة الدفاع أن القوات الجوية والدفاع الجوي لدولة الإمارات العربية المتحدة نجحت منذ بدء الهجوم الإيراني، في التعامل مع وتدمير 137 صاروخاً باليستياً و209 طائرة مسيّرة أُطلقت باتجاه أراضي الدولة، مؤكدةً الجاهزية العالية لمنظومات الدفاع الجوي وقدرتها على التعامل مع مختلف التهديدات.

وأوضحت الوزارة إلى أنه ومنذ بدء الهجوم تم رصد 137 صاروخاً باليستياً إيرانياً تم إطلاقه تجاه الدولة، حيث تم تدمير 132 صاروخاً، فيما سقط 5 منها في مياه البحر، كما تم رصد 209 طائرة مسيرة إيرانية، وتم اعتراض 195 منها، فيما وقعت 14 منها داخل أراضي ومياه الدولة، وتسببت ببعض الأضرار الجانبية.

وشددت الوزارة على أن هذا الاستهداف يُعدّ انتهاكاً صارخاً للسيادة الوطنية وللقانون الدولي، وأن الدولة تحتفظ بحقها الكامل في الرد على هذا التصعيد واتخاذ جميع الإجراءات اللازمة لحماية أراضيها وشعبها والمقيمين فيها، وبما يضمن صون سيادتها وأمنها واستقرارها ويحمي مصالحها ومقدراتها الوطنية.
