Is your opinion and I respect that.
In my opinion with Electron I have all JS frameworks to make any UI like React, Angular, Vue and thousands of free UI components. I have hardware acceleration as well, audio, video.
I currently use big Electron apps to work like Slack, Mail Spring, and VS Code.
And my PC has only 8 GB of RAM and run all of these apps and more at the same time. Automatic updates are common in that Electron world. Setup of applications with less permissions (no setup is run as admin usually).
There are security updates, if there is a security problem GitHub will report that in your repository and you can fix them, only updating.
If you can't design with HTML and JS something you can do in Lazarus is not my problem. I can and I do it well, and in no time thanks to open source.
