Life teaches you so many lessons, and having it all at once will never feel as good as working hard towards a much bigger goal.

I tell them to work hard and to start from the bottom is the best way to appreciate the wins they will have in life. Every job I had, whether it was cleaning bathrooms (my first job as a janitor) or working as a full-stack engineer at an XR / Robotic simulation company, needs to be taken seriously.

It really hits different when you are invited to a meeting at Meta with a variety of VPs and directors.

I still feel like that kid who came to the US barely speaking English, and just knowing how much opportunities my own kids have in this country really excites me.

AI is indeed an extension of us, and it shouldn’t take over completely if you don’t want it to.

Today, I worry about losing that, but to avoid those thoughts, we need to remember that AI is not a replacement. AI is an assistant. We can still re-structure the generated code, we can still write it from scratch, and have a co-pilot help with sections.

I remember when I started as a junior developer how much admiration I had for senior devs who had memorized exactly how to write complex systems from the ground up. They could code non-stop without having to do much research, mainly due to their prior experience.

The stuff I was able to create in just a few hours blew me away. Now, all I want to do is build. Knowing how to code and having an incredibly powerful LLM has changed everything for me.

Today, I did the exact same thing & lost track of time. I was playing with Unity AI Gateway (Beta), Meta MCP Extensions, and Claude Code.

I used to pull all-nighters constantly coding and prototyping games. I remember going to bed at 3-4 AM and waking up to my day job at 7 AM. I was much younger when I did this consistently.

📈 We remain the largest investor in VR, and we’re building both platforms to support the long term success of our creator and developer communities.

📌 Read the full details in Samantha Ryan’s post: developers.meta.com/horizon/blog...

Starting in 2026, VR and Worlds will operate as two distinct platforms:
- VR is focused on third-party developers, with the Meta Horizon Store restructured around apps and games instead of Worlds.
- Worlds is going mobile-first, with dedicated tools to build for mobile.

📣 Today I’m excited to share an IMPORTANT update on where we’re headed with VR & Worlds.

Over the past year, we’ve listened to feedback from developers and creators. One thing was clear: both communities needed more focus and clearer direction.

Hello Everyone!👋👓

I work fully remote in XR, so I’m usually indoors building prototypes. I’ve been testing the Oakley Meta Vanguard AI Glasses for a few weeks, and they’ve been surprisingly interesting. Excited to share why.

If you’re feeling stuck and can’t seem to push content out, think about the areas you’re truly passionate about. The motivation will happen organically, and your audience will appreciate it even more.

I love creating videos about tech I’m genuinely interested in, not videos made just to generate views. Honestly, that’s what makes content creation such a rewarding experience.

Now I’m curious 💡 is this the kind of wearable you could see fitting into your running, biking, snowboarding, or other routines?

ℹ️ I go over the reasons why I decided to buy these, and I show a variety of demos while using them during my new running routine. I also picked up the Garmin Forerunner 165, which integrates really well with Meta AI.

📌 The project shown today is available on GitHub github.com/dilmerv/AIBu...

Let me know if you have any questions.

This works by taking our LLM callback response and sending the generated text to ElevenLabs or OpenAI TTS using our Text-to-Speech agent, allowing us to turn AI responses into natural-sounding audio that works across multiple platforms.

Hello everyone! 👋👓

Today, I’m continuing my AI Building Blocks series in Unity by adding Text-to-Speech features to our existing LLM prototype. This honestly makes the prototype feel more vivid.

Also, it is extremely important to spend time on packaging, as it doesn’t matter how great your video is if your title and thumbnail do not attract people.

I don’t talk a lot about my #YouTube video creation process mainly because I like to keep my content very focused on XR. But for those of you creating conventional content, make sure by all means to use the A/B Thumbnail Testing features; crazy how 📊 CTR increased drastically just with a few tweaks.

Nothing like working out very early in the morning. I personally didn’t want to come to exercise, but every time I tell myself to push through by waking up early and working out hard, then my day becomes extremely productive.

I will be speaking at #GDC and this time my part will be focused on XR + AI, honestly we have some really cool stuff to show you! Stay tuned for more info about the talk.

Today, I'd like to share a new course that was created to help you build your experience for the Meta Horizon Store. This course covers preparing your dev account, verifying your organization, & choosing a platform for your first build.

Athletic intelligence is about to hit different.

AI in your glasses, hands-free capture, real-time help, open-ear audio… we’re entering the era where your gear actually thinks with you.

This changes how athletes train. Mark this moment. 👀🔥

#meta #oakley #tech

I’ll be speaking at #GDC again this year, and I’m prototyping something this weekend to make sure I’m very familiar with the tools I’ll be showcasing.

Hello everyone! 👋👓

Today, I’ll show you how to use 𝐋𝐋𝐌𝐬 𝐢𝐧 𝐔𝐧𝐢𝐭𝐲 𝐰𝐢𝐭𝐡 𝐀𝐈 𝐁𝐮𝐢𝐥𝐝𝐢𝐧𝐠 𝐁𝐥𝐨𝐜𝐤𝐬, powered by AI features available in Meta SDKs v83 and later.
