Context, Graphs, and Semantic Layers
In “Understanding Context“, Bill Inmon and Jessica Talisman argue that context is a human-led social agreement that must be maintained.
Humans decide what counts as context and what constitutes knowledge. The work is sociotechnical by nature – the deliberate alignment of human knowledge practices with the systems built to extend them.
Context is to AI what data was to BI, Prukalpa argues: the raw input that allows the system to function.
She draws a parallel between semantic layers that came before, and context graphs that everyone is looking to get now. The parallel points out failure modes for semantic layers: misaligned incentives, migration math and the execution path.
Context graphs are framed as a trillion-dollar market. So the trillion-dollar question is – will this time be different?
Foundation Capital’s thesis argued that vertical agents will own context because they “sit in the execution path”. The sales agent will capture renewals context, the support agent will capture escalations context, and so on.
This quietly assumes there’s a single execution path where context naturally accumulates. Prukalpa argues that’s true for simple workflows, but not beyond that. Most decisions happen across workflows and systems, and context comes from everywhere.
Heterogeneity is moving up the stack today, from a mess of data tools to an ever growing mess of AI agents, copilots, and applications. This means that while execution paths may be local, context is global.
If context graphs are going to live up to their promise, we’ll have to learn from what worked and did not work previously.
Prukalpa offers four principles to make the context layer a reality beyond the hype:
1. Built for human collaboration, not just machines.
2. Machine-native and built for change.
3. Open, portable, and bigger than any single vendor.
4. One shared brain, many agents.

@ednewtonrex I was just gonna tweet about, and saw the news broke out yesterday only. See screenshot co-pilot referencing a YouTube video
Me on the way writing for my own understanding, and co-pilot knowing exactly my thoughts come from a @3blue1brown video. 🤯
@Vijayvns777@IndiGo6E@Ministry_CA@DGCAIndia@JM_Scindia Also since it’s a codeshare flight I believe, the connection should be fine on some other Turkish plane. But there would be lot of hassle u might have to with. Also make sure the checkin baggage is correctly tagged whichever connection is made due to the delay.
@Doofensmirtz19@Go4_TLI@MKBHD Everyone in my relatives which are above around 40 have been vaccinated here in India. India is going very strong in a phased manner, since it is a large country it will take time. Also wait for corporate vaccination drive is just around, which will bring it masses
Two key comments from @elonmusk yesterday.
"The number one limiting factor for growth is good people"
"If there is one thing I'd like to come out of this call is that a lot of great people want to join @Tesla"
Build companies that inspire.
Recruiting is extremely important.
