Andrej Karpathy’s 1-hour Stanford lecture on AI engineering is one of the best explanations I’ve seen of how AI systems actually work.
The progression is simple:
10% → LLM
30% → Prompt
50% → Agent
70% → Loop
100% → Graph
The key takeaway:
AI engineering isn’t just about writing better prompts.
It’s about building systems around models — giving them context, memory, tools, feedback loops, and data flows.
“Delete everything, keep Graph.”
Definitely worth watching if you’re building with AI agents.

the reason i didn’t like calculus and linear algebra in college is simple:
i was learning the math before i understood why i needed it.
• matrices were just grids of numbers.
• derivatives were rules to memorize.
• eigenvectors were something you calculated for an exam.
• jacobians were another ugly matrix.
then i got deeper into robotics, ai, physics, and control.
suddenly:
• matrices became transformations between coordinate frames
• derivatives became motion and rates of change
• jacobians connected joint motion → end-effector motion
• eigenvalues started telling me about stability and system behavior
• gradients became the machinery behind optimization and learning
the math didn’t change.
the context did.
sometimes you don’t hate a subject.
you just haven’t found the problem that makes you need it yet.
When you see babies in Christ! lol
Please enjoy your season o. And store up prayer for yourself in this season, as you will need it for when communion and fellowship becomes hard;
Scriptural backing? Know this:
There won’t be need for a comforter if you never go through emotions;
You appreciate the way maker more when all roads are blocked and you almost gave up, then He showed up.
God understands our emotions more than we know; for we do not have a high Priest who isnt touched by the feelings of our infirmities…
The Bible says “and David encouraged himself in the Lord”
When Paul wrote about how Alexandre the Coppersmith has did him much evil, it was from a place of pain;
When he wrote about how Demas has left him, it was from a place of hurt
But yes, when those seasons come, it is your fellowship with Him that sustains you; thats when He shows up as comforter!
I took this counsel. Did everything to make it a reality and I owned my own house by June 2020. Two months after my 40th birthday, it changed everything about my life and finances.
Guys, whatever they say, try and own your own house by the time you turn 40. Even if it is one room, let it be one room somewhere on this earth that you own. You can choose to rent it out and be a tenant elsewhere, but have a house to your name.

There’s a high chance your first few lectures will make you feel dumb. You’ll question the validity of your Nigerian degree and even wonder why you chose grad school in the first place. 😂
You’ll see classmates from other parts of the world confidently engaging the professor while you’re still trying to grasp the content.
It’s imposter syndrome. But Má fọ̀! You just need to lock in. You’ll catch up! 💪🏾😂
Nigerian-American engineer & Harvard grad Yinka Ogunbiyi built HaloBraid, the world's first braid-assist robot, easing strain on stylists & saving salons time. $7M raised, 7,000+ salons waitlisted. American innovation, global impact. #AmericanExcellence in action.
