Windows NT on 600MHz machine opens apps instantly. What happened?

A lot of people are bringing up Wirth's law or other things, but I want to get more specific.

Has anyone else noticed how bad sign-on redirect flows have gotten in the past ~5 years?

It used to be you clicked sign in, and then you were redirected to a login page. Now I typically see my browser go through 4+ redirects, stuck at a white screen for 10-60 seconds.

I'm a systems C++ developer and I know nothing about webdev. Can someone _please_ fill me in on what's going on here and how every single website has this new slowness?

The last time I logged in to AWS, the process went something like this, I may have left out or mistaken a step or two:

Go to login page

Solve capcha to get to login prompt

Enter user name, get sent to next page

Enter password

Enter MFA code

Failed, try resynching MFA token

Repeat login process

Failed, try rescynching MFA token again

Failed, repeat login process and then go to troubleshoot MFA link on mfa page

Enter password again

Go to altternative factors link

Click link to send verification email

Didn't get email, click link again

Click link in verification email

Click link on login page to get a phone call with a code

Get a call but it doesn't give me a code, try again

Still no code, try again

Get a code this time from the call but the code fails verification, try again

Get a code and it gets verified, sends me to a login page

Solve a capcha

Enter username and password, get logged in

Fortunately, I have found a solution to ensure this series of issues does not reoccur.
