Legalfly CEO Warns AI Slop Creates More Work
Legalfly CEO Ruben Miessen warns that generative and agentic AI is flooding the legal sector with 'AI slop,' creating more work than it saves. Citing a Politico report, he notes that the US House Office of the Legislative Counsel spends more time fixing flawed AI drafts than rewriting them. A Stanford/BetterUp survey of 1,150 US office workers found 40% received sloppy AI-generated work, each taking nearly two hours to fix. Miessen argues that general-purpose models like ChatGPT or Claude are misused for legal drafting, causing excessive redlining and errors. He advocates for AI tools that follow a firm's defined playbooks, editing with precision rather than rewriting entire contracts. Legalfly, founded in 2023, offers such workflows and has raised over €17 million from investors including Notion Capital, Redalpine, and Fortino Capital. The legal AI market is competitive, with Legora valued at $8.8 billion and Harvey as a leader, but Miessen's critique targets poorly applied general tools.

Workslop: AI-Produced Trash Increases Office Work
A Swiss article reports that rising use of generative AI at work is creating low-quality outputs—coined 'Workslop'—that colleagues must correct, increasing workload and costs. Citing a GoTo survey, 77% of respondents say reviewing AI-generated work takes more time than checking human work. Workday estimates nearly 40% of time saved by AI is lost again, with corrections averaging two hours per incident. Swiss ombuds offices report weaker, foreign‑law citations in AI‑generated complaints; Bank Ombudsman Andreas Barfuss warns of inflated customer expectations, and Insurance Ombudsman Martin Lorenzon expanded his legal team due to added workload. Swiss insurer Suva is investing in better detection tools to counter AI-assisted fraud attempts.
AI Disrupts Legal Billable Hour
Artificial intelligence is reshaping the legal profession, with nearly 90% of legal professionals in the U.K. and Ireland now using AI, according to Clio's Legal Insights Report 2026. Among firms using AI, about 80% report handling more work without extra resources, and over 70% say it cut costs by automating administrative tasks. This is challenging the traditional billable hour model, as tasks that once took hours now take seconds. Major firms like A&O Shearman and Slaughter and May are deploying AI tools like Harvey to speed up document review and regulatory analysis. The report indicates about one in five firms with wide AI adoption struggle to meet billable-hour targets, and Deloitte predicts the share of work billed by the hour will drop from 72% to 44% in two to three years. While routine work is most affected, complex work still requires human judgment. Firms are also rethinking junior lawyer training, with a focus on skills like connecting diverse areas to solve complex problems.
AI 'Slop' Floods Content with Little Productivity Gain
Gary Marcus argues that generative AI has produced a large volume of low-quality output across apps, books, music, scientific papers and web content—what he calls "slop"—without delivering material productivity or GDP gains. He cites graphs from the Financial Times and The Washington Post and references studies from MIT, McKinsey and Bain suggesting limited ROI for many companies. Marcus highlights rising token costs and cash losses at major AI providers (Open AI/OpenAI, Anthropic, Cursor, CoreWeave), noting an analysis that suggests providers may be spending far more than they charge. He also cites the Leiden Declaration — an open letter from mathematicians reported by the New York Times — warning that AI can produce plausible but unreliable proofs. Marcus allows that coding may be an exception, but questions long-term durability given the high operating costs of foundation-model providers.
