He found the necessity of intricate programming languages like HTML* (sigh) for creating webpages overly complex and exclusive to programmers. He envisioned a supercomputer that understood his design intentions in human language, eliminating the need for typing or coding. It seemed like a far-fetched sci-fi dream at the time.

He becomes selflessly nice in a relationship and at work avoiding conflict and doing what is needed for everyone, except himself, to be happy and content. This more often than not comes with the expense of suppressing his own true emotions and feelings.
- [Thoughts on Flutter vs. Native App Development](https://teemusk.com/flutter-vs-native/): During the last 10+ years that I’ve built mobile applications, there have been many different cross-platform or even “no-code” solutions to build mobile apps.

I have built production apps with the first two, so I have extensive experience with cross-platform systems from the past.

At the time I compared three tools, Jenkins, CircleCI and Bitrise, and landed on Bitrise. Five years later I'm still running Bitrise on my projects, so that verdict held up. But the landscape has grown since then. Xcode Cloud didn't exist yet, GitHub Actions wasn't really a serious option for iOS, and half the people who find this page are actually searching for things like "Swift vs CircleCI" that need clearing up first.

- [Why Build an App?](https://teemusk.com/why-build-an-app/): Developing an app has become a cool thing to do for businesses. It reminds me of the days when everyone had to have a website.

It is okay to cherish your idea of a perfect business venture and a technological innovation, but in reality a good idea counts for a tiny percentage in success. Especially when it comes to developing the next Instagram or Whatsapp.

They might be artists in real life, but when they are doing a gig they are pleasing a client. While art might consider the aestethic sense of the society, it still is mostly personal. Client work is not.
