With 400 daily users in the CRM, mysql is not a problem at all. The only problem I have is loading huge tables sometimes without using pagination, but that's from a connection speed problem to the user not a mysql problem. Sometimes the table makes it towards 10+ megabytes and thats a bit goofy.

My question was more based on should I learn the new tech, or any new tech, if I'm now building something I hope will have atleast several thousands daily active users.

Deep down I know the answer. It's pretty obvious mysql won't have problems even for a million users for most types of sites.

If your high end user estimate is in the thousands, scaling is less of an issue. If users haven't mentioned frustration with latency, it's probably not a problem.

That said, you still have to feed your creativity and curiousity. I try to carve out time for "not totally necessary but skill growth and potentially impactful" time.

I happened to be sitting in front of a JavaScript book as you wrote that.

I finally opened it. I was always curious if I should learn js/node to replace PHP and maybe even get away from server side rendering in php. Right or wrong, from what I've read I think I can put that to rest for now. I see just as many issues with doing things in JS as PHP. Just spending a few hours of reading let my brain move on from that curiosity for now.

Good tip you gave. Thanks
