Share with your CTO
Software engineering is mid-reset, and the velocity of change is itself the story. Business Insider’s six-part series on how AI coding tools are reshaping the profession found that the industry swung from uncapped AI experimentation to cost containment inside a single month. Companies like Uber and Amazon ran token-use leaderboards to maximize AI adoption, then pulled back weeks later as costs spiraled. Engineers are now functioning as AI output reviewers rather than writers of original code, and the entry-level pipeline that produces senior talent is quietly breaking.
What this means for your business
The token reckoning is the leading indicator your engineering budget planning needs to account for now. Uncapped AI tool access sounds like an investment in productivity, and it is, until it isn’t. Uber’s COO flagged runaway token spend as unjustifiable in May; Amazon killed its internal usage leaderboard shortly after. Any CTO who hasn’t built consumption governance into their AI coding rollout is one enthusiastic quarter away from the same conversation.
The deeper structural problem is the hollowing of the junior developer role. Senior engineers extract the most value from AI precisely because they have the judgment to catch its mistakes. That judgment gets built by doing the work AI now does: debugging, writing simple features, reading unfamiliar codebases. If AI absorbs those reps entirely, the profession loses its training ground. Call it the apprenticeship gap: the tools that make today’s senior engineers more productive are simultaneously preventing tomorrow’s senior engineers from forming. Your talent pipeline is thinning in a way that won’t show up in attrition metrics for two or three years.
The tradeoff is real: AI coding tools deliver genuine throughput gains today while degrading the conditions that produce experienced engineers over time. The signal worth watching is whether your organization’s AI-assisted code review burden is growing faster than your team’s ability to catch the errors it generates. If reviewers are approving AI output they don’t fully understand, you’re not faster, you’re just accumulating technical debt with extra steps.
Concept deep-dive: Tokenmaxxing
Tokenmaxxing describes the practice of maximizing AI model usage volume, measured in tokens, the discrete chunks of text a model processes and generates. It emerged from the logic that more AI interaction means more productivity. Companies operationalized it through leaderboards, turning consumption into a competitive metric. The analogy is running every employee’s laptop at 100% CPU utilization and calling it productivity. Tokens cost money per unit, and unconstrained usage compounds fast. For engineering organizations, token spend is now a real budget line that requires the same governance as cloud compute costs.
