747-400`s future

I managed to escape Japan and Im in the UK now. I got to fly the KLM 747-400. The 747-400 I have to say is very vey strong against very very strong turbulence. Over Russia since I was at the very back it was shaking a bit but the pilot said it was very very sever winds outside. There was clouds at 32,000 feet. At the end as the plane flew and the most turbulent place (the most northly route over russia) it was really shaking so hard even the crew had to sit down. At the end of the flight I got to go cockpit and the pilot said be glad your flying on the 747 because the turbulence would have been worse on other planes. Also the co pilot was very young, he was 22 
That was a great time

coming to think for my next booking, is the 747-400 eqquiped with anti turbulence technology? And most importantly is it good. The 777 has it I belive but was not good. The last time I flew a 777 words cannot describe how bad the 777 was against turbulence
and why is the back bumpy?

747 forever:
Please do not discuss anti turbulence technology any further. This is a highly classified subject and you are placing yourself at great risk by disclosing it to the wrong people!

. But why is it that secret? This is not about A vs B, wait... AHA!!! NASA

Just though of something crazy, what if the 747-400 had two engines. Like one and four removed. Would it be more efficient than the 747-8 or 777? It would not carry as much as it would with four however but good for low weight flights Also when will the first 747-8 be delivered? I have a feeling it will before the 787

I'm certain someone has considered the 747 twin possibilities, but here are some of the issues involved:
GE has used their 747-100 testbed to wring out many different development engines, installed in the #2 position. One problem is the great diameter of the GE90-115B means there is very little ground clearance, and so if the left wing is a bit low on landing, the nacelle can scrape the runway. This presents a real problem in a left crosswind, surely unacceptable for an airline's ops.
And all the 747 electrical, pneumatic, and hydraulic systems are predicated on four engines. This would mean a major design change to switch to two donks.
