• Co-sign Dave & Jon are media personalities with pointed views because that travels even though plenty of room for reasonable debate in between. For most of us debate is a waste of time. We have bills to pay not crusades to fight. Pick whatever view makes your life better.

• How large is Snowflake's AI revenue? Management lowered product gross margin guidance from 76% → 74% due to "fast-growing AI workloads." If GPU inference runs at ~25%–35% gross margins, that 200 bps compression implies ~$60M–$75M/quarter (~$240M–$300M ARR) in direct AI token consumption.

  Quoting@cursor_aiYou can now run Cursor cloud agents on your infrastructure, including pools of machines that automatically scale with demand. This lets you give agents access to internal services or specialized hardware, while the agent loop stays in Cursor.
