Salesforce is NOT planning to turn off Classic next year. They are highly encouraging people to migrate, but there is not a set date. I was in a training last week with Salesforce where they covered this and indicated that they did a poll out to their customers. The general consensus was that most customers needed at least 2 years to convert. So that gave Salesforce a good litmus test, but they did not actually set a date from that.
For the October deadline, I've done some pretty extensive research on this and the swithc isn't going away either. What's happening is this: Salesforce will turn on Lightining for all orgs. Does that switch your users? Not unless they are under a profile that gives them access to lightning, which is all standard profiles, but it is generally not standard practice to use the standard profiles as an operating user profile. You should clone them and then customize to fit your business.
Also for the October deadline, once a user has access to Lightning, they will be swapped back to Lightning from Classic on a weekly basis to encourage them to make the transition. This does not impeed their ability to swap back to classic.
Here is all the documentation:

Release Notes for Spring 19: https://releasenotes.docs.salesforce.com/en-us/spring19/release-notes/rn_cruc_lex_turned_on.htm
This update starts appearing under Critical Updates on January 28, 2019. The update begins auto-activating on October 12, 2019.
All users with the Lightning Experience User permission enabled are affected by this critical update. This includes all users with standard profiles and users with custom profiles or permission sets that have the Lightning Experience User permission enabled by an admin.
Salesforce will turn on Lightning Experience on a rolling basis starting in Winter ‘20 to empower users to move faster, do more, and be more productive.
To encourage everyone to work in Lightning Experience, users working in Salesforce Classic are switched to Lightning Experience on a weekly basis. Users can switch between Salesforce Classic and Lightning Experience from the user profile menu.
