It feels like there's a Cambrian Explosion of new vibe coding apps. Every day I'm seeing some new competitor to Lovable and Replit that claims to do it better. In the end, the winner here is going to figure out how to scale distribution. Getting someone to use your app is way…
My prediction here is that Amazon acquires Anthropic to avoid being left behind in the AI race. They’re unlikely to win, but this puts them in a good position to stay in third place.

Some clarifications that make the situation for existing h1b’s far less dramatic. The situation for new h1b for foreign born US graduates has sucked for a while, so this policy change may be far less impactful in the short term. But as always, new policy communication is all…

This is a disaster for the tech industry. Effectively shuts the door for skilled immigration by raising the cost of a foreign worker by at least 2000%. Many senior people in tech have been here on h1b visas for 10+ years and this cost increase will encourage companies to…

Prayers for Charlie Kirk and his family. This kind of violence is never the answer even if you disagree with someone’s politics.

This isn’t surprising to me at all. In some tech companies, there are two groups of people who make things dysfunctional. 1. People who literally don’t do shit. 2. People who actively block others from doing shit. The latter unfortunately creates more of the former. The…

I've spoken to a lot of folks in tech who are trying to land an experienced eng manager job. I was there myself about a year ago and dealt with the job market first hand. Starting in about mid 2022, there was a push to flatten tech orgs and eliminate a lot of middle management…

Almost two years ago, I suggested that India and China should set aside their regional differences for economic reasons. Interesting to see that US tariffs in 2025 have created the conditions now to bring Modi and Xi together.

I have been feeling this for the past year. Tech is getting older. It’s more people in their 30s and 40s than people in their 20s. In 5 years, many of us will be in our 50s. We will see a different kind of ageism. I wouldn’t send my kids to get a CS degree now unless they were…

Very telling to see that even with billions thrown at their own AI image gen models, Meta finds itself partnering with @midjourney.

We've gotten so used to each new frontier model being so ground breaking compared to previous models that any new model with mixed feedback looks like a flop. GPT-5 is definitely suffering from this, but I wouldn't be surprised to see the next releases from xAI and Anthropic…
The adoption of e-commerce style data collection by more traditional retailers has some interesting side effects. I've gotten 3 feedback request emails from Lowes asking me to review the tape measure that I purchased in store last Saturday. Apparently it has zero reviews.
A lot of tech companies are paying for every engineer to have AI tools like Cursor. Engineers I've worked with have asked me if I think it will negatively impact their performance if they aren't using these tools. My response has been simple: in the long term these tools will…

Good thread. Most social apps have a very different feel during their growth stage where the engagement is community-based. Contrast this with an app’s monetization stage which is based on showing ads or using paid gamification. At this stage, addiction-based engagement wins…

The next wave of vibe coding is emerging in Big Tech. Teams are experimenting with bringing vibe coding workflows to their proprietary tech stacks to improve the productivity and speed of engineers. Some are going as far as to empower non-engineers too, but I am more skeptical…
