Agreed. When you program in machine language and optimise every single step, you can do amazing things with low resources. Sadly, today much of the software we use seems to grow to take up all the resources, with terrible optimisation. That said, the software is far more complex I guess. My first computer at 1k of RAM... was amazing how clever some people got writing code for it!

3270 terminals were _highly_ intelligent,_ having their own CPUs and "display programming language". Combined with CICS, they were an early form of client-server web computing, where the end user types everything into the terminal and then pressed the XMIT (aka Send) button. That transmitted the whole block of data to the mainframe. Until you pressed XMIT, the mainframe completely ignored you. This is in stark contrast to minicomputer OSs like Unix/Linux and VMS, where the OS must process each and every keystroke and cursor movement. Bottom line: web-based client-server computing is just a new and horribly inefficient version of a programming paradigm that's been around for *55 YEARS.*

The IBM mainframe does not have to keep an separate active program for state for each user. When I used to program CICS, back in the 1980s, you could store context in hidden areas on the user's terminal and/or in something call TSQ - Temporary Storage Queues. When the user pressed SEND, the CICS program would fetch the context based on the data from the user, do the work and return a new screen image back to the user. I do some PHP web programming these days and my programs are designed very much like a CICS program since there are cookies that come from the user and I can thus restore the context, do the work and return a page back to the user. The web server needs to remember little of a particular user's transaction. The web server has the equivalent of TSQs with session info. The comment about OS processing every keystroke is possibly true for a UART connection but I think Ethernet sends info in blocks(?) It is definitely not "... horribly inefficient ..." Computer folks are not going to make badly designed web servers.

In this day and age of solid state storage, are spinning rust disks considered sequentially accessed media? You still have to wait for the disk with the correct data to rotate and pass under the read/write heads, whereas solid state truly is random access, as there is effectively zero latency for access.
