This question becomes irrelevant if you want to work on technology.
If you want to work on latest technology you need to acquire the skills first. Only bars on your acquired skill and you capability to learn you will get an opportunity to work on best technologies.
And if you want to learn based on the opportunity company provides, you are out of question for that company.
Employers look to use your skills and not train you or facilitate you to learn. However for a learned and skilled person employers provide opportunists to become experts in that skill.
And definitely in today’s world the employees are expected to learn on their own before companies can give opportunities to use those skills.
