When Meta announced 8,000 layoffs and keystroke tracking in the same week, it revealed the core mechanism of AI job displacement. Capture the inputs an employee receives and the outputs they produce, and the machine will figure out everything in between — and replace them.
Where this was said

Wright builds his most original argument in this chapter: the training process behind modern AI is not merely a form of machine learning in the conventional sense — it is a form of accelerated evolution. Just as biological natural selection, through trial and error over millions of years, built cognitive machinery into human brains, AI training accomplishes the same feat in compressed form using human-generated data. Nobody told the machines what words mean; they figured it out. Nobody architected the semantic structure; the training process reverse-engineered it. Wright uses this to correct a fundamental error he himself made when he first wrote about Hinton's neural network work in 1983 — he had assumed that meaning would need to be manually programmed in, dictionary entry by dictionary entry. He was wrong. The key revelation: all you need is data, and the machines do the rest. Wright then grounds this in the present tense with the Zuckerberg anecdote — Meta announced 8,000 layoffs and keystroke tracking of remaining workers in the same week, illustrating the exact mechanism: capture what goes in and what comes out, and AI will replicate whatever cognitive process happened in between. The implication for employment is stark and near-term.
AI training processes reverse-engineer cognitive functionality that took millions of years of biological evolution to develop, doing so purely through data.
Mark Zuckerberg announced 8,000 layoffs and keystroke tracking of workers in the same week — illustrating how AI input/output data enables automated replication of cognitive labour.
AI independently invented edge detector neurons to recognise visual objects — the same solution evolution built into biological brains.
AI systems have independently invented edge detector neurons — the same solution biological evolution arrived at for visual object recognition. This is convergent evolution happening between silicon and carbon, the same phenomenon that gave crabs their form and flight to birds and bats.
SiteGPT attracted over 1 million visitors and $500K in total revenue without spending a cent on paid marketing. The secret: engineering as marketing — building free tools that rank on Google.
Bhanu quit his first job after just 8 months, moved back to his parents' house to cut costs, and started building. One product sold for $250K; the next hit $10K MRR in its first month.
90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competition keyword and funnels users back to the paid product.
50,000 monthly visitors become 200 leads, 60 trials, and roughly 15–24 new customers per month at ~$100 average revenue each. Add a $1,700–$1,800 LTV and you have a very healthy SaaS.
Start with a blank Ahrefs search, layer in keyword filters (include term, KD < 10, volume > 1,000), list candidates in Notion, design a CTA linking to your main product, then score by volume, difficulty, build effort, and product relevance. That's the whole playbook.
Marketing feels painful for most builders. Engineering as marketing flips the script: instead of writing cold emails or blog posts, you build things — and those things rank on Google forever.
Don't spend months perfecting before launch. Ship the core feature, get real users, and let their feedback dictate the product roadmap. Premature polish is a trap.
SiteGPT launched and hit $10,000 MRR within its first month. That momentum was so overwhelming that Bhanu sold his existing SaaS, Feather, for $250,000 to free up all his time.
PropGPT launched with 20 downloads a day and strong influencer marketing but hit a ceiling at $1,000–$2,000 MRR. High download numbers masked a critical flaw: almost nobody stuck around after the free trial ended.
