I've been working in Software Dev for a long time and have been managing different teams. I am also deeply involved in the community and work with many different organizations, teams and companies. There are 0 teams that don't use AI. 100% of them are fully integrated and every single developer uses it.
Also, since coolmath games are mostly earning money from people that are not coders and the users of coolmath games hate AI(cause AI had and will replace many jobs and other reasons) so Coolmath game has the need to create a reputation of not using AI since this offer is public. Maybe they use AI in secret/private situations, I don't know and I don't care.
Yeah, I get that, but it's not realistic. AI came and it's not going anywhere. Anyone that thinks someone will write manual code again after a few years has no knowledge of the industry. I think Jensen Huang (Nvidia's CEO) said it best - developer's job has always been about solving problems - everything else are tools. Like at some point people that knew how to manually write Regex were highly respected and needed, then people automated it and now nobody knows how to manually write regex and nobody will ever need to.
