Tech Pulse 4/20/26

This week on Tech Pulse, we narrate four articles spanning AI-assisted personal finance, space communication technology, battery repurposing, and AI's acceptance in journalism.Most people using AI for financial advice are doing it wrong — not because the technology can't help, but because vague prompts get vague answers. An MIT professor walks through what a strong prompt actually looks like and how to pressure-test what comes back.NASA tested a laser communication system on Artemis II that moves data roughly 100,000 times faster than Apollo-era radio. The achievement is real — but the piece asks the harder questions about whether promising space tech ever escapes the lab.Rivian is turning retired EV batteries into the largest automotive on-site energy storage system in the U.S. The project reflects a boom driven by AI data centers and electricity prices that won't stop climbing.Journalists are warming to AI — until a plagiarism incident complicates the optimism and forces a more honest conversation about guardrails.
