**Natalie Pistunovich:** But then I will include the question on the difference from mlops to aiops. \[laughter\]
**Johnny Boursiquot:** Right...
**Natalie Pistunovich:** Then I guess comes the fun part... Unless, Johnny, you want to ask anything before we start talking about the unpopular parts.
**Johnny Boursiquot:** Let's get to the unpopular stuff.
**Natalie Pistunovich:** Alright.
**Jingle:** \[41:07\] to \[41:22\]
**Natalie Pistunovich:** I don't know if I'm supposed to say this, and I'm sorry if not, but the performer of this wonderful song has a birthday today. Finally turning 18. So if you see Mat on Twitter... \[laughs\] Wish him a happy birthday. But only if you're listening to the live recording. Actually, you know what - ...
**Johnny Boursiquot:** He's finally an adult.
**Natalie Pistunovich:** \[laughs\] Maybe he'll grow up.
**Johnny Boursiquot:** Maybe he'll grow up. \[laughs\] That's an unpopular opinion, I guess. Mat, we love you very much. It's all in good vibes. Mike, do you have an unpopular opinion for us?
**Mike Eastham:** Yes, I have an unpopular opinion. It's not tech-related, which I hope is okay, but...
**Johnny Boursiquot:** It's all good.
**Natalie Pistunovich:** That's not popular.
**Mike Eastham:** I really just don't like maple syrup, is my unpopular opinion. Even on pancakes, on waffles - I just don't do it. That's my opinion.
**Johnny Boursiquot:** Okay...
**Natalie Pistunovich:** Johnny, I saw a tweet from you from the weekend that you were making pancakes.
**Johnny Boursiquot:** Yeah, yeah. You know, I have young kids, and they love themselves a pancake, especially the syrup, so... \[laughs\]
**Mike Eastham:** It seems almost universal... Just not for me.
**Natalie Pistunovich:** What don't you like about it, Mike?
**Mike Eastham:** How sticky it is is a big part of it.
**Natalie Pistunovich:** Is it more or less sticky than honey?
**Mike Eastham:** Somehow it feels more to me... I don't know if that's chemically accurate, but that's my perception anyway. And we've got a lot of Canadians working at Tecton actually; in fact, the CEO is Canadian, so... I hope if they hear this I don't get ostracized.
**Johnny Boursiquot:** \[laughs\] They'll be like, "Oh, you don't like syrup, huh?" Well, there you have it. Unpopular opinion.
**Natalie Pistunovich:** Yeah. I think the most funny opinions we have is in the context of food, so... Great choice for an unpopular opinion. There will be a Twitter survey; we will see how unpopular is your unpopular opinion. You might get into the top five, or low five
**Mike Eastham:** Are you supposed to have the most people disagree with you?
**Johnny Boursiquot:** I mean, it's a goal... We all have life goals, so why not this one?
**Mike Eastham:** Okay. Hopefully I do well then.
**Johnny Boursiquot:** Mm-hm.
**Natalie Pistunovich:** Cool. Alright, well that was a very interesting conversation, and I think it's a rather new field, at least in our context of gophers, this mlops in general, but also feature stores in specific... And we will be providing links for you to learn if you wanna dive into that, or if you wanna contr...
**Johnny Boursiquot:** Indeed.
**Mike Eastham:** Thank you for having me.
**Natalie Pistunovich:** Thanks, everyone.
**Johnny Boursiquot:** Alright, y'all.
