you just have at least one reviewer in there that's specifically targeting like don't overuse lets or lambdas or crazy things um i don't know all the bit in between the co-work the co-work co-pilot studio great but for the financial modeling community it feels like that's the only answer surely that you've just got a team of agents doing this stuff
31:16
I think if you do that, I think you do need to have a large chain and it does need to be trained to like really look for some really silly things.
31:24
And I'll give an example.
31:25
Like, so I, in the last few days, like a U shortcut, like there's a new model type that we need in my company.
31:30
And it's been on my to-do list.
31:31
It's like, you know what? I'm just going to point shortcut at it and I'm going to see what it does.
31:35
A, to save me some work and B, just out of curiosity, because I've not used it like in anger before.

7 MINS LATER

And maybe you want to have 50 adversarial review agents pick at it and comment and question the assumption and whatever but i do think there's something that you get if you build the entire thing yourself that is hard to replicate
31:04
I- all the bit in between, the co-work, the co-work, Copilot Studio, great, but for the financial modeling community, uh, it feels like that's the only answer surely, that you've just got a team of agents doing this stuff.
31:16
I think if you do that, I think you, you do need to have a large chain, and it does need to be trained to like really look for some really silly things.
31:24
And I'll give an example.
31:25
Like, so I, in the last few days, like I used Shortcut.
31:28
Like there's a new model type that we need in my company, and it's been on my to-do list.
31:31
It's like, you know what? I'm just gonna point Shortcut at it and I'm gonna see what it does.
31:35
A, to save me some work, and B, just out of curiosity 'cause I've not used it like in anger before.

7 MINS LATER

But I, I do think there's something that you get if you build the entire thing yourself that is hard to replicate in review mode.

[laughs]
134:07
That's a great question.
134:09
Uh, I think it would've been when I was about seven or eight.
134:11
I think for some reason I decided I want to, wanted to put the 2002 World Cup in Excel.
134:18
I mean, somebody else had already done this, 'cause somebody else was running the tournament, but I decided that seven-year-old me could do it instead.
134:24
Uh, that's my earliest memory with Excel, but, um, yeah, since then, uh, sort of built a career doing various things in Excel, and it's now a competitive esport for reasons that I still don't really understand, but, uh, it's, it's fantastic.
134:37
There's a great community around it.
134:40
Mm-hmm.
