From AI to SI. Nothing changes.
1) Changing the label from AI to SI will not decide which jobs disappear. Capability, cost, and adoption will.

NVIDIA reported $96.221B of quarterly revenue, up 106% year over year.
Data Center revenue was $89.023B, up 117%.
But one direct customer represented 16% of quarterly revenue.

He said: "I worked very hard, every day, nearly no rest, and finally I saved $5K. And the rest? From my mum."

Oracle booked more than $30B of additional AI-cloud contracts, taking RPO to $664B.
But it also completed a $20B common-stock sale during the quarter.

A good investment thesis needs a kill condition.
Write down:
• what must be true
• what you will monitor
• what would prove you wrong
If you cannot name the failure condition, you are defending a story—not testing a thesis.

If AI gives you a valuation, ask which assumptions are doing the most work.
Then change each one.
What happens if growth is lower? Margins stay flat? The multiple contracts?
A valuation is only as strong as its assumptions.
