• Faster processors - 1,000 Mhz or more (SPARC, Merced, PowerPC, ???)
• More Memory and Disk - 1 gigabyte RAM becomes common, 10 Gig or more disk drives are common on the desktop.
• Much better human computer interfaces.
• Quantum Computing and other new computing methods.
• Superfast Internet
• Java-like languages

• Easy multi-computer computing. Mathematica tasks allocated over as many computers as are available.
• Blackboard interface. Users can create equations or other calculations and pick any terms or parts of terms, order them in any way, just as if they were written by hand. Placed anywhere on the paper.
• Easy collaborative computing over networks. Multiple colleagues can work on a calculation and view results simultaneously.

To finish up, I started this talk mentioning that I first started serious scientific computing using a slide rule to analyze data from nuclear magnetic resonance experiments. Just as I was preparing this presentation I found something very amusing to me in the most recent Scientific American.
