Amateurs obsess over tools, pros over mastery

I had a boss that would constantly chase the new buzz-worthy tech rather than focusing on the tools and languages we already used and supported (which also had the capability of accomplishing the same objectives). My team spent a lot of resources on half ass implemented tools that created more gaps than what it was supposed to fill. In the end, the team (not him) were expected to fix the issues he created because he was always busy chasing the ‘next big thing’, brushing the issues he created for the team under the rug. Super frustrating and glad I’m not working in that environment anymore.
