At a lot of companies, asking "can I have a week to play around with these new tools/frameworks before I get started with them" will be met with "no way". Of course, not saying that's good: often the new tools are strong enough that you would still long term get massive development time savings even with the upfront costs. But a lot of managers and PMs are only focused on "shipping" ASAP, never mind the technical debt or maintenance costs (and to be fair, sometimes you need to ship ASAP... but sometimes you don't)
I think the comment still stands though, if you can't master the new tools including for reasons like the company not giving you time to learn them then maybe you (the company) should stick to the old tools.
Doesn't apply if the new tools are forced by management, but often it's the developers driving new tech.

That's the reality I was trying to capture with my original comment.
For example if you're moving from on-premise servers or a simpler cloud provider (Rackspace, Digital Ocean, or Joyent) to AWS there is no way to escape learning AWS, and the last thing you want to do is manage everthing through the web console so you will need to learn a new tool to manage the infrastrucutre when your old tools don't work with the new stuff.
Management and sales types hear about how great, fast, and agile the cloud is and don't consider that it also takes some time to do things right, and there's is no way around learning lots of AWS specific bits at the very least.
