@Tutanota@mastodon.social as someone who's been a paying tuta user for ~1.5 years and who's recommended it to countless others (and who is also a software developer), i would like to caution you: there's a very large risk that your developers feel more productive, but in actuality aren't getting much more work done at all. there have been multiple studies about this: study 1, study 2. even anthropic themselves (who are very biased!) found that using AI caused a "statistically significant decrease in mastery" when learning a new skill, while not producing a statistically significant speedup. so i question the idea that ai use could allow your engineers to implement features they otherwise wouldn't have time for; the science certainly does not support such a claim i'd like to ask that you also heavily consider the environmental/ethical implications of AI use. the technology (both training and inference!) is responsible for a massive increase in nonrenewable energy use, which is accelerating the climate crisis and significantly worsening pollution in communities near data centers. this seems to really go against your focus on sustainability; using AI to develop tuta doesn't seem like "put[ting] ethics before profits". there's also the issue of stolen training data - companies have taken the work of open source developers, authors, artists, etc and used it to build a system with the goal of replacing those very people's jobs, concentrating all the wealth generated from their work into a couple massive tech companies instead of a bunch of individuals. i appreciate you discussing this in the open, and i'm sorry that a ton of people are overreacting to this (although i can somewhat understand why they are). i really hope that you decide not to use AI in tuta development; tuta is a product i really care about and i don't want to see it worsen in quality/contribute to the climate crisis/become reliant on big tech companies. i honestly think you could win a lot of customers over by leaning on how your product is "ai-free" in your advertising :)
