It's interesting how you can look down on front end for being new and naive while suggesting that Google is a fine reliable tech stack provider.

I'm the opposite of everything about this post. A very experienced dev (>20 years professional experience) that has moved primarily to the front end recently in my career (gradually over 4 years). I won't touch flutter simply because the sole vendor and essential dependency is Google.

Fads are present in every corner of development. As is "not invented here" or the general draw to green field.
