This is the Harry Potter fan fiction author, right?

Okay.

I think that there are still people out there who are convinced that LLMs cannot write good code.

Oh, boy, yeah.

Those people are in for a very nasty shock in 2026.

I do not think it will be possible to get to the end of even the next three months while still holding on to that idea that the code they write is all junk and it's like any decent human programmer will write better code than they will.

That's exactly what I'm saying, yeah.

And honestly, that's a gimme.

I could say that one today.

I think here's one that's AI adjacent.

Okay, yeah.

I think this year is the year we're going to solve sandboxing, right?

The challenge we need, like I want to run code other people have written on my computing devices without it destroying my computing devices if it's malicious or has bugs.

We have so many technologies for this right now that are almost, almost something you can use by default.

Like WebAssembly solves this kind of thing.

There's containers and all of that sort of stuff as well.

I think we have to solve it.

It's crazy that it's 2026 and I will pip install random code and then execute it the way

I don't want to run a piece of code on any of my devices that somebody else wrote outside of a sandbox ever again.

Why would I do that?
