I am going this way too. I recently tried to onboard a few contractors with limited python experience. It took several deep sessions to work out why they couldn't get an environment set up. After 10+ years I've never come across the install certificates command. There's still no way to get a dev environment with a specific version of Python working with one command that works reliably everywhere. pyenv isn't even packaged for Linux, you have to install from source.

This, plus Typescript's superior type system makes it very tempting for application development.

However I'll probably wait until there's a really good Jupyter Notebook equivalent...
