We have been trying to build distributed agent orchestrators at Google since last year. There are various options, not everyone is aligned&#8230; I gave Claude Code a description of the problem, it generated what we built last year in an hour,&#8221; she <a href=\"https:\/\/x.com\/rakyll\/status\/2007239758158975130?s=20\">posted <\/a>on X.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" fetchpriority=\"high\" decoding=\"async\" width=\"640\" height=\"360\" src=\"https:\/\/i0.wp.com\/officechai.com\/wp-content\/uploads\/2026\/01\/maxresdefault-1024x576.jpg?resize=640%2C360&#038;ssl=1\" alt=\"\" class=\"wp-image-58181\" srcset=\"https:\/\/i0.wp.com\/officechai.com\/wp-content\/uploads\/2026\/01\/maxresdefault.jpg?resize=1024%2C576&amp;ssl=1 1024w, https:\/\/i0.wp.com\/officechai.com\/wp-content\/uploads\/2026\/01\/maxresdefault.jpg?resize=300%2C169&amp;ssl=1 300w, https:\/\/i0.wp.com\/officechai.com\/wp-content\/uploads\/2026\/01\/maxresdefault.jpg?resize=768%2C432&amp;ssl=1 768w, https:\/\/i0.wp.com\/officechai.com\/wp-content\/uploads\/2026\/01\/maxresdefault.jpg?w=1280&amp;ssl=1 1280w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p>&#8220;It&#8217;s not perfect and I&#8217;m iterating on it but this is where we are right now. If you are skeptical of coding agents, try it on a domain you are already an expert of. Build something complex from scratch where you can be the judge of the artifacts,&#8221; she added.<\/p>\n\n\n\n<p>&#8220;Building at large companies is hard right now due to the legacy infrastructure. 10-15 years ago, some of these companies were building in house to be frontier. Today, what&#8217;s available internally is too disconnected from what&#8217;s available outside and is often years behind,&#8221; she said.<\/p>\n\n\n\n<p>Dogan acknowledged that she was using a competitor&#8217;s product while still at Google. &#8220;This industry has never been a zero-sum game, so it\u2019s easy to give credit where it\u2019s due even when it&#8217;s a competitor. Claude Code is impressive work, I&#8217;m excited and more motivated to push us all forward,&#8221; she said. Google interestingly is an investor in Anthropic, and Anthropic <a href=\"https:\/\/officechai.com\/ai\/anthropic-google-tpu-deal\/\">signed a major deal<\/a> with Google to use its TPUs for its computing needs.<\/p>\n\n\n\n<p>This anecdote is yet another datapoint of how coding &#8212; even at top companies &#8212; is being disrupted by AI. Just last week, Claude Code&#8217;s creator Boris Cherny had <a href=\"https:\/\/officechai.com\/ai\/claude-code-creator-says-he-didnt-open-an-ide-all-of-last-month-used-claude-code-for-all-his-coding\/\">said <\/a>that all his code in the past month had been written by Claude Code. Anthropic CEO Dario Amodei has <a href=\"https:\/\/officechai.com\/ai\/my-prediction-of-ai-writing-90-of-code-is-already-true-at-anthropic-anthropic-ceo-dario-amodei\/\">said <\/a>that 90% of Anthropic&#8217;s code is now being written by AI, and Google had <a href=\"https:\/\/officechai.com\/ai\/half-of-all-code-at-google-is-now-generated-by-ai-google-cfo\/\">cited<\/a> a 50% number a few months ago, and Microsoft had <a href=\"https:\/\/officechai.com\/ai\/30-of-the-code-at-microsoft-is-now-being-written-by-ai-ceo-satya-nadella\/\">come up<\/a> with a 30% number earlier this year. And with top Google engineers saying that a single AI program is doing more in an hour than an entire team had done in a year, it does seem that human-written code could very well be a thing of the past in the coming years.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>AI is now besting some of the best engineers in the world at writing code &#8212; and that too by a wide
