@NUFC @ChelseaFC @SpursOfficial @ManUtd I was right that United would miss out. (They finished 8th.)

[IAmJamesGreaves @IAmJamesGreaves]

Meanwhile, 27 sports pundits @BBCSport predict the @premierleague season and all pick the same 4 teams. https://t.co/uRZfdr1ZMJ. No way. Groupthink at its finest. None of them will be correct.

[IAmJamesGreaves @IAmJamesGreaves]

There's no way one of @NUFC , @ChelseaFC , or @SpursOfficial don't break into the top 4 and ruin the parade. Maybe a couple of them. Are @ManUtd really so strong that 23/27 put them in the top 4? They missed out twice in the past 5 years alone.

[IAmJamesGreaves @IAmJamesGreaves]

Turns out the pundits were mostly right about the 23/24 Premier League season after all.

[IAmJamesGreaves @IAmJamesGreaves]

@james406 We are hiring for 3 of these.

[IAmJamesGreaves @IAmJamesGreaves]

I only used to have to get up at 5, cold plunge, drink white Monster and work at a standing desk. Now I have to get up at 3, check my 67 AI agents, write a long X post about how you're using Claude Code wrong, and then go over to LinkedIn and tell everyone AI is already better at being them than they are. #Exhausting.

Breakthroughs don't come from incremental thinking and behavior. Everyone wants breakthrough, but incrementalism is the safe option. It's crazy to act incremantally and expect breakthrough.

VItal to work out what the user is actually trying to solve. Default human behavior is to project our own cognitive and behavioral shortcomings onto something external. Software is a great target

@miragemunny People with >10 drafts:

0.00072% of DAU

This would be the worst engineering-to-impact ratio in the known universe.

Better thing I’d like to solve:

why aren’t you just posting those drafts when inspiration strikes?

[IAmJamesGreaves @IAmJamesGreaves]

@CBSEveningNews I really hope this is true. America deserves a clear-thinking free press. We need it.

This year I choose connection. Happy 2026 everyone

@bcherny The event horizon only happens when there's no more people in the loop. People take time to adjust. Whole groups of people, even more so.

I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

[IAmJamesGreaves @IAmJamesGreaves]

@levie Love this. You can't just use the new tool in the old way. Just as steam power let factories spread horizontally, away from a central shaft, AI is reshaping how knowledge companies are set up. Good insight here by @levie

@draprints This is gold for Gov sales. All the data is out there, but few are using it well.

[IAmJamesGreaves @IAmJamesGreaves]

@dshaw 💯 Sales is now an engineering function, and vital to close the learning loops; Those that can implement, learn, adapt, re-implement the fastest will win. Need multiple cycles, not just one and done.

[IAmJamesGreaves @IAmJamesGreaves]

AI's no silver bullet—it's exposed our weak spots and forced upgrades in people and processes. My take: Bet on foundation over flash, and build teams that adapt without the bs. What's your top AI lesson from '25? Reply or DM your take—open to swapping war stories. #AI2026 6/6

Building on the other great SaaS reviews, here's my take as a tech CEO sifting through our 2025 AI "strategy." The five biggest lessons learned: (Thread 1/6)

[IAmJamesGreaves @IAmJamesGreaves]

Humans plus AI is still the accelerator right now. Humans for direction because AI will still sidequest hard. Based on this I need less english majors and more engineers: people who think in data, systems, process and docs. Every function is now an engineering function. 5/6

[IAmJamesGreaves @IAmJamesGreaves]

I'm enjoying the end of year AI reviews from @jackclarkSF, @ivanhzhao and others. A lot of smart people trying to work out where we are going.
