@mtylerjr - I think that Silicon Valley is starting to suffer from age or otherwise has become uncool which is inevitable given the maturing process of companies, so I don't tend to pay much attention to them as I maybe once did.
Buckets of technology are interesting but really it comes down to a simple question of is it better to be a jack of all trades or a king of one. I run into lots of folks who claim that they are experts in a number of different areas which makes me laugh, but really the term 'expert' is so loosely used anymore that it really has become meaningless. Real expertise comes from years of practice with completion of multiple challenging projects, which just isn't done anymore so clearly the plan is to be the jack of all trades, which really falls into line with the mentality of FOMO (fear of missing out) and people hopscotch between different technologies so fast anymore that it keeps the skill bar pretty low.
I'm old and don't really care anymore but I prefer to be an expert in a single technology such that I can build pretty much anything using that technology and don't need all these supporting minion technologies. I'm having lots of fun with UWP (using C# of course) and have been picking projects which target different areas of UWP such that in about three or four years I'll be able to accurately claim a junior expert level and be able to code pretty much anything using that technology. Right now I'm getting schooled in In/Out Process BackGround Tasks and Triggers in UWP for a heavily IoT flavored project I'm working on (with a side order of SQLite). If you aren't learning something new everyday, then you'll never make it to expert, but I'm a journey guy and destinations are brief viewpoints between journeys so in about five years I'll be looking for something new to master.
I get bored with different technologies and like to move on to learn new things. Today I had a company approach me about some security based IoT stuff, both areas I had some expertise in but that was yesterday and I've moved on to new challenges.
