Do you think moving to Rust would help you make enough money to retire in the next 3 years? If yes do it. It will definitely help you save the rest of your life and spend more time with your loved ones.
If you think Rust doesn't really matter for that and you can even do that with PHP and it's the problem and the execution that matters then focus on building a great product instead of getting into the Hype wagon and missing out on the bigger picture of what really matters.
The appeal is to existing contributors or people who are interested in open source and wants to work on this space. I am not either of them nor use the product.
Folks interested in this space and actually wants to work on open source, now is a good time to fork Lang chain.
The moment they raised VC funding the open source project is dead. All their incentives are now to 100x the investment they just raised. They would start putting core features behind an enterprise license.
Contributors of langchain please fork the project and make a better project! Stop sending free contributions to make the investors rich.
A lot of technically smart people over analyze everything and don't take any decisions that are non deterministic.
You can also say many technically smart people are also heavily short sighted and misses the big picture.
That's why you need the Jobs. Steve Wozniak by himself would have not started any kind of company and not remotely a company like Apple.
So the ones who are courageous, takes the risk and have a big picture vision gets the money.
Also the reason why many technically smart people never gets laid.
