Burning a few tokens to inject current time into the system prompt probably doesn’t have a meaningful ROI for 99.9% of queries.

Suspect LLMs will monetize well in the business space for multiple years before it'll monetize easily in the personal / hobby space (they're viable for a number of real business use cases today, personal feels 2026+).

Neo4j failed miserably when we needed “large graph” (single digit petabyte) at crowdstrike in 2014/2105
Building it atop cassandra wasn’t that hard, but all the off the shelf stuff was laughably bad in some dimension (titan, neo4j, etc).

It’s missing one pretty important thing though - the Jan 2025 inflection point correlates strongly with arxiv.org/abs/2501.12948 which demonstrated that efficient gpu optimization combined with aggressive post training could yield massive savings and decent result
DeepSeek-R1: Incentivizing Reasoning Capability in LLMs via Reinforcement Learning
We introduce our first-generation reasoning models, DeepSeek-R1-Zero and DeepSeek-R1. DeepSeek-R1-Zero, a model trained via large-scale reinforcement learning (RL) without supervised fine-tuning (SFT)...
