Look. I'm not an idiot. I write open source. I love free and open web.

Google login works. We use use Gmail - it works. We use google classroom - it just works. Most websites offer Google Login - it just works.

When you have 30 students and you waste 2 minutes logging into a website -- that is 2 x 30 == 60 minutes of student learning lost. Little things like that add up.

It's not 60 minutes of learning, it's 2 minutes of learning. 2 minutes went by. You're not running a factory so you don't need to use factory-style productivity metrics. Anyway what's the hurry? What could be so crucial that not a minute can be spared? Maybe this is why school is uninspiring? The feeling of being on a breakneck treadmill, never having time for anything? Education shouldn't be about quantity, it's about quality. But I know what you're up against.

Come now. On one hand, tech ensures that things get faster, and we ask why a second could be important?

In yesteryears, no one could compute the things our phones do today in seconds.

But the demand for time has gone up, not down. Now idle time is a target to "get stuff done".

Even on HN, people have complained about how being idle during idle moments is a luxury, since everyone is on a treadmill to see how hard they can perform even in leisure.

The point being that when things just work, other long term issues being invisible, people will go for the cheaper option.

The same way people have burnt fossil fuels because the costs are sent off to the future, they will choose convenience over security.

Having worked IT at a college, I can tell you that it's very important to get every minute out of your class. When your class is only 60 minutes, and you spend the first 2-10 minutes getting logged in every single time, that's a huge chunk of wasted time. People are paying one way or another to be there, sitting there staring at a spinning cursor doesn't make anybody happy.

School is a funny old place. I'm struggling to be honest because I'm a hacker at heart and think like you.

But being observed by senior management, they would see students not learning. You could expect extremely close scrutiny for the next few lessons. To be put on special measures. Not quite a sack-able offence, but ....

Perhaps you should consider being less defensive. I believe (could be wrong) OP asked a genuine question and was interested to hear a response. S/he didn't call you an idiot or question your love for the free web.

I think your last paragraph would be sufficient to explain your reasons along with a single, "it just works."

Their response was perfectly reasonable and interesting.
