Good day.... Here are the three tech stories worth your attention this Friday, 23 October 2026.

1. Ghana plans its own AI computing facility

Ghana's Minister for Communication, Digital Technology and Innovations, Samuel Nartey George, says the government is building a national computing facility to give researchers, universities and industry the computing power needed for AI development. Speaking at the JoyNews Digital Economy Forum on 21 October, he said phase one should be completed within 24 months. The government is acquiring the data centre and equipment through the Public Procurement Authority.

The aim is to reduce Ghana's reliance on computing services bought from providers outside the country. The minister described it as an important first step rather than a complete solution.

2. Walmart opens its store to AI shopping agents

Walmart announced on 21 October that it will let AI agents shop on behalf of customers, with new controls to keep people in charge. Agent Profiles, due within the next month, give each AI agent its own profile inside a customer's account, so its purchases appear separately. Shoppers can require approval for every purchase or let an agent buy within a spending limit, with examples such as $50, $100 or $200.

Walmart is also testing an invitation-only Agent Gateway for developers, and has set rules for agents: they can't access card details or change payment methods. The move comes a month after Amazon blocked Meta's Muse assistant from buying on its site.

3. Micron chip workers strike in Taiwan

Workers at Micron's Taoyuan operations in Taiwan went on strike on 22 October after months of failed talks over profit-sharing. In an early October vote, 1,994 of the union's 2,258 members backed the action. The union wants 15% of Micron's operating profit set aside for quarterly employee bonuses.

It matters beyond Taiwan: the island is a key production base for the memory chips used in AI servers, and Micron has warned that the current memory shortage could last into 2028.

The bottom line

Today's stories share one thread: the fight over who builds, controls and benefits from the infrastructure behind AI, from national computing power in Accra to shopping rules in the US and chip factories in Taiwan. See you tomorrow for another briefing.
