Google finally feels threatened after dominating search... What follows short-term losses when creative destruction begins [Z1 News - Part 2]

An independent exercise, not a statement by the video creator or verification of every claim in the video.

Separate profit from displaced searches and newly generated AI searches

This hypothetical calculation does not use actual company figures. Suppose 100 legacy searches each generate revenue of KRW 1 and variable cost of KRW 0.2, producing contribution of KRW 80. If 20 searches move to AI search with revenue of KRW 0.6 and variable cost of KRW 0.2 per interaction, the remaining legacy searches contribute KRW 64 and AI searches contribute KRW 8, totaling KRW 72. Usage is unchanged but contribution falls. Adding 20 genuinely new AI searches on the same terms contributes another KRW 8, restoring the original KRW 80. This shows why total usage growth must be separated into displaced usage, its profitability and genuinely incremental usage.

Check for yourself

  1. How much of AI usage growth replaces legacy searches, and how much is genuinely new?
  2. Does advertising or commission revenue per interaction exceed inference and service variable costs enough to offset lost legacy contribution?

Limits of application

The search counts and KRW amounts are assumptions, not Google’s actual unit revenue, costs or forecasts. This contribution comparison excludes fixed research and development, depreciation, capital expenditure cash outlays, taxes and separate changes in traffic acquisition costs. Ad availability alone does not establish equal profitability.

What to look for
Examine why retaining users through AI search may not preserve the profit from existing search advertising, and compare cloud growth, capital expenditure and deal reports through company-specific monetization.
Why it matters
Separate usage that replaces an existing service from newly generated usage and calculate contribution per interaction to identify when more usage increases profit. Also distinguish segment growth, cash-flow measures and definitive transaction status when reading earnings releases and deal reports.

Timeline

6 segments
  1. The speaker raises the risk of AI replacing existing ad-supported searches, but Google’s official guidance says ads can appear in AI Overviews and AI Mode in certain countries and languages, making a blanket claim of no ads in AI search incorrect. The official results also describe the highest Search query growth rate in the last five years, rather than a fivefold increase in search volume. Evaluate displaced searches, newly generated usage, advertising or commission revenue and inference costs together; transaction-fee-funded agents are not automatically free of conflicts of interest.
