Coding Assistants Move From Autocomplete to Agents
The newest developer tools no longer just finish your line — they open pull requests, run tests, and iterate. We look at whether the hype holds up.
Marcus Okafor🇺🇸 Industry & Business EditorJun 28, 2026 5m readAutocomplete was the training-wheels era of AI coding. The new generation of tools wants the keys to the whole workflow.
From suggestions to actions
Instead of proposing a snippet, agentic assistants now plan a change, edit multiple files, run the test suite, and surface a diff for review. In small, well-tested repositories the results are genuinely useful.
Where it still breaks
Large, under-documented codebases remain hard. Agents confidently refactor things they do not fully understand, and the cost of reviewing a wrong 400-line diff can exceed the time saved.
- Best results: greenfield features, test writing, migrations
- Weakest results: sprawling legacy systems with implicit conventions
The verdict: treat these as fast, tireless junior engineers who need a firm review process, not as autonomous replacements.

AI's New Scarcity Is Power: Energy Vault Lines Up 1.25 GW for a Texas Hyperscaler
Energy Vault's new strategic agreement to deploy 1.25 GW of integrated power infrastructure for an unnamed hyperscaler's Texas AI data center puts hard numbers on the industry's changing bottleneck. The company expects $500 million to $600 million in revenue through the second half of 2026 and 2027. But the customer, commercial terms and execution details remain undisclosed, making this both a significant infrastructure signal and a project whose risks cannot yet be priced cleanly.
